Hello.... I suffer from anxiety and feel like I am losing my myself in anxiety and depression.
I currently have something going on with my liver, I have to wait for the 25th before I get to see a heptaologist... everyday that passes I feel worse and worse.
I worry all day everyday, I can't think of anything else. I can't smile for 2 seconds and I am becoming very depressed. I cry many times a day, either because I'm in pain, not feeling well or am just so worried that I feel completely hopeless.
I try and tell myself that worrying over it will do no good as I can't really do anything about it but I am a mother of 3 so not worrying is hard.
My appt to see specialist has been long and I still have a few more weeks of waiting and I seriously can't take feeling like this anymore, I just can't take it 
To settle down, go to YouTube and search for guided meditation for detachment from overthinking. There are many to choose from besides this one and they completely calm down my mind and body. They teach us how to separate negative thinking from ourselves.
fear has gotten a hold of you but you don't have to let it. Fear is worry about the future and the what if's . And yes it is a complete waste of time. I did that for 20 years and it wasted a lot of my life. Nothing bad ever happened. Don't do that to yourself. Fear is a useless emotion because the future does not exist yet. It is not based on fact but it is a series of fleeting negative thoughts made up by your mind. Chances are you will be perfectly fine.
mindfulness teaches us that when we get a negative or anxious thought, don't try to fight it off. What you do is calmly acknowledge the thought for a few seconds, and then imagine it floating off and dissolving. Do this every time you get a fearful thought. If you try to fight it off you will become more anxious.
The other thing is focus on your breathing. Inhale long and slowly through your nose making sure your stomach rises. Then exhale slowly through your mouth like you're blowing out a candle. Focus on how the air feels coming in and going out and the sound it makes. This keeps you in the present moment, away from your fears. Do the meditations a couple times a day especially when you're laying down to sleep. Hope you feel better
I've seen your post on another forum regarding your liver worry and really can understand your fear of the unknown while waiting to see your consultant. I think we we would all struggle with this kind of fear. The best thing to do is keep yourself very busy, definitely don't google as you will end up thinking the worst. None of us know what's going to happen tomorrow, just concentrate on today, being mindful. Accept that's it's ok to be fearful, you are human, acknowledge it and let it go. The what ifs keeps the anxiety going. From the sound of your post you're thinking the worst scenario and that's what's feeding your fear. The advice from Jan re
