i totally understand, u can talk to me if youd like i feel exactly the same and i also have no idea what to do but i cant keep going on like this. im 16 and i basicly have no friends nor do i ever go out  if anyone has help or knows how to deal with this please let me know

I'm chiming in because I too feel the same and that you are not alone.  Depression/anxiety, as you know, affects everything.  I too am an introvert and it's to my detriment. Most people wish they had as much time as I do, but, what they don't know is that it's spent in my head.  In terms of answering your question as I too feel isolated and sad, for me, just writing this to someone else who suffers like I do is very helpful.  Often, I feel so alone, like there's so much out there to do, but, I just can't bring myself to doing it.  I take medications, practice deep breathing, stretch (don't know yoga, but, know stretching is really good for one), prayer, write and see a counselor.  I have a hard time reaching out to my friends because I feel like I should be 'doing more' and that maybe I"m 'lazy'.  Although, I was diagnosed with clinical depression/anxiety years ago.  My thoughts go out to you and I hope you are feeling better.  ;)
