Feeling Extremely Hopeless Please HELP

So for about a week now ive just been off. I feel as though everyday is a struggle to survive. I went to the doctor a few weeks ago I believe now and they told me I have high cholestorol which i talked about in a previous post and im only 25. Every since then Ive not felt well at all i keep looking up things on google that tell me im basically going to end ip stroking out or having a heart attack from this so ever since i found out i keep thinking my heart is giving out. Ive begin to have hot sensations through my body, Jaw sensations like tingles and also i have times where it feels like something is going on with my heart and i feel pains there. I have back pains headaches you name it. I was fine before i went to the doctor but finding that out has really took me down hill. Ive been making changes to how i eat and exercise so im hoping to get my levels right. I had a Xray done and they said my tests were fine and showed no signs of bad heart but how reliable is that if something was wrong wouldnt it have shown, but why dont i Feel fine. I constantly look up signs of heart attack and stroke because of my arm and jaw pains. I also read that EKG dont tell if I could have a Angina or other heart problems so the EKG i got i feel wasnt accurate by saying nothings wrong so what if they missed a underlying heart condition I even called the office and they told me nothing was wrong I still dont belive it because what if they missed something. I suffer from horrible anxiety but can anxiety really make me feel this bad. I feel like at any moment im going to have a heart attack im always fearing for life everyday its awful. One time i was convinced i had a tumor because of a excruciating headache i had one day then suddenly that went away now here are a new set of symptoms. Im so upset because i just want to feel good again. What should I do.? I go to the doctor again monday because i need talk to him about these symptoms to put my mind at ease.

in a word, yes. Anxiety can cause all of your symptoms. but it’s not just anxiety. It’s the constant feeding of negative thoughts and fears to your brain which produces more adrenaline and more anxiety.
it’s like a merry-go-round. Fear , Negativity, and what if thinking go round and round in your head which strengthens the fear and anxiety along with all the googling. what you are doing is strengthening your anxiety and fears control over you. I know it’s difficult but it is what it is. I’ve been there I’ve done that and I finally realized that it’s up to me to manage better.
im guessing that when you see your doctor, he or she wont find anything wrong. The doctor will tell you that the tests were all normal. you could go through all kinds of testing and still the odds are that nothing will turn out. That’s when we have to realize that it’s not a physical health condition causing the symptoms. except for severe anxiety and stress.
i highly recommend that you visit a counselor for this. It’s very difficult to do alone. It’s mental torture to live like this alone. there’s a great book that I read that really helped me a lot for my anxiety. It’s called finding quiet. It really put my mind at ease and I found peace. take care of yourself

thats true its like no matter what I do i still feel unwell I just woke up from a nap still feeling bad thinking something is wrong with me its such a vicious cycle. Im trying my best to learn how to get my mind to not think so much
