Nods...
I know exactly how you feel. When I'm properly medicated, I tend to not even feel like looking at my electronic-keyboard...let alone try and compose something (I do this as a hobby, nothing serious).
I also a LOT of times feel like i am at a loss as to who I am, where I am going and where I want to be. Granted, I think of suicide wether on med's or not but I know that if I were to go off of them, my depressive mood might sink sooo low that I might just act on it (which I haven't done as of yet...touch wood).
Some days I just feel like running far...far...far...away and just disappear. Go and live on some secluded island where I can just "be"...if that makes sense...It feels like I won't be able to be me, so lang as I am "chained down" by other people's expectations?
At any rate, the most I can do is sympathise with your situation as I my self have a daily struggle at keep head above water. On the outside it might seem as if tho I am cool calm and collected and haven't a care in the world and that everything in my life is going according to plan...but deep down...there is a storm of epic preportions breweing all the time, just waiting to erupt...
I wish you all of the best...and if you need to, my shoulders don't mind getting wet...
