I just feel like why we HAVE to bear it? Like what was the need to make me born? I really don't understand.

I feel like someone is literally choking me all the time, my heart feels heavy all the time, I'm always tired, I don't enjoy doing things I like anymore....
I don't even want to do it..
I don't even interested in life. 
I can't end it cause I don't have the guts to do it but sometimes I realise that how close I'm to take my permanent leave.
