You're concentrating on hurting others? Come on now. That is not why all the bad things happened to you, but if you carry on focusing on why others can't be brought down to your level, instead of why you can't bring yourself up to theirs, then problems will begin to arise from that and you will only have yourself to blame.
What you've been through is awful. I get you because even small things when happening all at once can really spiral you out of control.
I went through similar, no abortion, which must be very taxing emotionally, but things like housing issues, parental issues, relationship issues, that all compounded to send me into a literal nervous breakdown.
When I came out of it I didn't look around and ask 'why can't others suffer like me' instead I asked 'how can I get my life back on track?'
Now my life was waaaay off track. I was doing bad things to cope, I could have gone so far as to end my own life with what I was doing.
Today I'm living a life that I am truly enjoying every single day. I am thankful for what I have. I have a home, it's all mine, I work again and am good at what I do, I am married!!! Okay that all sounds benign but it really isn't for someone like me.
How did I turn my life around so drastically?
I concentrated on me, not others.
