For about 3 months i've been so confused about how i was feeling mentally. One second life is dandy and i couldn't be happier to be alive and I would think to myself about how things couldn't get any more perfect. But maybe 1 day later all the feelings of happiness just goes down the trash, everything. and i have this feeling of being "stuck". (Thats the word I think best describes it) I feel isolated even though I have many great friends and I do go out a lot. I feel as if I need to "get out" of my body like being in my own body if too suffocating and I need to breathe. I've never thought about suicide and i don't think I ever will; but my feelings always clash and contradict themselves and its driving me nuts. I just don't know what to do anymore. I am 19 years old, pretty good to mediocre life so far and I just don't know what the heck is going on.
