I know i am posting alot but I'm going through a really tough time. I feel strange like i am confined deeeep inside myself. I keep thinking I have a heart condition and I went to the doctor and my blood tests are normal. And I have no one to talk to who even understands in my family or friends. I feel isolated and depressed and I have noticed when I am depressed and negative my anxiety is HORRRRIBLE. And I can't fight my depression. Please help.
