is life really worth it?

I have been depressed and cutting myself for a year and 3 months. i am always feeling down, unwanted, and useless. my life has hit rock-bottom.

i am always having suicidal thoughts, i can be having a good day injoying myself but the thoughts are always there. i constintaly have dreams of hanging myself and jumping off bridges. like i dont know what to do life just sucks

my father drinks heavy and i think that is the reason i am so depressed. i have been spending a lot of time at friends places and staying there for a few days. that really helps.
