It's currently 6 am while I'm writing this and my anxiety has kept me up all night, I've probably gotten about maybe one to two minutes of sleep today and I'm not even sure of that, really. My anxiety was always a common occurrence in my life. I would have a hearty amount of social anxiety, actually it was pretty severe. I also would have health anxiety and panic attacks which happened mostly at night, to which I believe must be some underlying fear of the night I must have, but sometimes it would happen in the middle of the day for no good reason. The mornings were pretty bad some days too, before school I'd wake feeling like I had something wrapped around my neck. Now, about four to five days ago at this point, I can't quite pinpoint exactly when. I had a terrible nightmare that stayed in my mind, at first as soon as I woke up I felt fine. I went about my day fine did my daily things had my normal dose of anxiety. Suddenly, the day after, extreme worry and feelings of guilt with no reason to be guilty hit me like a smack in the face. I began to think that the dream I had wasn't something a normal person should and that I would maybe become a perverted or insane person who would be locked up in a mental hospital for the rest of her life. A very big fear of mine is turning out like those people you see on the street that are talking to themselves or rocking back and forth that scare you, It gives me extreme fear that I'll turn out like one of those. My dream set that off. Now, I've been having very, very severe anxiety all day everyday for the span since the worry and guilt hit me until present time. The dream was about my little brother and it disturbed me, even though I'd never do such things that occurred in the dream and I know that it isn't real, my anxiety makes me panic nonetheless. I get anxiety walking by my little brother, or even thinking about him. I'm pretty sure it's because he's a constant reminder of the dream which leads to my 'I'm going to go insane and be sick' obsessive thought. So from then on everyday as soon as I wake up through the whole day, I feel as though I want to cry and just keep on crying, I feel extreme worry and guilt, I feel as though I'm going insane and I won't ever be my normal self again, I can't sleep considering it's 6:30 now and I don't feel tired at all and haven't gotten shut eye. This whole situation is really upsetting me because my mother is afraid I might be going insane and she cries which makes me feel even worse about myself, like I'm actually going to lose it. I don't have the same relationship with my family that i had before the dreaded dream, and now that I've had it I don't think I'm ever going to change. I don't intend to use medication for any of this because I don't want to become dependent on them and as soon as I get off them relive this nightmare. I really, really feel terrible every single day at all times since that dream. I can't watch tv or read my favorite book without getting distracted in thinking that I'm insane. These thoughts really are obsessive and severe. I don't know what to do, I feel like I'm at a loss and I won't be able to do anything to stop myself from losing it. I might look se my mother and the rest of my family, I might end up in a mental institution, I'm very depressed now. I hate feeling and being this way, this has truly made me hate myself and wish that I could've just been born normal instead of my mental illness ridden self. Please, I need some help and I would really appreciate all the help I can get. Thank you for taking the time to read this, I'm going to go back to trying to sleep now. Wish me luck 
Hi l think you need to go to your doctor and get referred for treatment.Medication is not the only treatment in fact therapy is better in the long run.Try to remember we have millions of thoughts every day however ànxiety takes our biggest fears and magnifies them.Get help and talk to your mother she is worried about you and wants to help but doesn't know how.
Hi Anon, sounds like your really struggling with this anxiety and depression. First of all I can assure you that your not going to go insane, the anxiety and depression does make folk worry they are going insane or mad, it's a common thinking style with the illness and does cause distress but what your thinking is "normal" for the illness, I've had these thoughts many times.
Regarding medication I don't think you will become dependent as you appear to have a strong will and the sort of person who would only take them to serve as a means to an end, CBT would be the best course of action for you but I wouldn't rule out taking medication to help you get better.
The dream you had has obviously affected you deeply but dreams are not reality, dreams are weird things and the way your concious thoughts of the day are filed away but often bare no relationship to what your thought were. Whatever happened in your dream is not and will not be or become reality, when the dream pops into your mind try not to dwell on it or ruminate over it in your mind, let it stay there for as long as it wants and you will find it drifting away, if you do dwell on it then that's ok also but do try and tell yourself it was just a dream.
Just to reiterate your not insane or going insane, you never will, you are not very well at the moment but it will go and you will be "normal" again. Have you been to see your Dr about all this? If not I think you should even if it's for reassurance but preferably to be referred for talking therapy or CBT, don't rule out medication although I know your reluctant to take them but you wouldn't refuse anti biotics if you had an infection.
Finally don't feel your alone in dealing with this, you've been brace enough to post here and you should continue to post as there is plenty support and advise available from people going through the similar things, we all suffer in our own way but support and help is available.
Keep posting!
PM me if you want too.
