There's virtually no enjoyment in life for me anymore :(?

First of all, I'm so sorry you have to go through all this. No one should. Secondly, wow, this totally sounds like me. I have gone through many similar experiences, especially not being able to go outside without freaking out and my family and friends not believing me/thinking I'm crazy. I have just gone through a period of life where I felt just like you do now-hopeless. There were times when I felt like I could just give up right then and there. But you know what? Now I am happy and mostly healthy, with just a few random "bad" days. I know you've probably heard all of these before, but find a hobby that you like, listen to music, read a book, do relaxation exercises, or anything else that you think may help. The hardest part for me was to stop the "what if" thinking. Letting go of my worries was difficult, but I tried my best to think and live in the present only. Dealing with my friends and family was also hard, but I tried my best to stop explaining most of my aches and pains to them, and told them that I was going through a rough time and needed help. Surprisingly, many were understanding. Another thing is don't be afraid of going to the doctor! I avoided seeing my doctor for a long time out of fear of having something terrible. One day, though, I went, and explained everything. Things I thought were terrible diseases were actually not. Some things I actually did have, but was given medicine which treated/regulated them. Soon it became no big deal. Nowadays, to relax myself, I talk to someone and distract myself. Distraction is the key! Try hard to do something distracting, even something boring. Anyway, I hoped I helped just a little, and hopefully knowing that someone else has gone through what you are going through now is at least a little reassuring!
