Abortion

So I just found out I’m pregnant having a really hard time deciding if I want to go through with an abortion, I just had a baby 5 months ago got really bad depression, me and baby’s father aren’t in a stable relationship I’ve practically raised her on my own up until a month ago when he started stepping up, I was taking the pill but just found out I am pregnant I feel like I won’t be able to cope I’m still struggling with depression now and sometimes I don’t feel bonded to my child but I’m trying.

He wants to keep it, I’m having a hard time getting my head around it

Advice please?
