Abortion help

I have a son who just turned 1 on the 4th of july. My SO and are still trying to get our lives together and be able to be completely independent. We are currently living in a three bedroom apartment with my mother and we are just barely getting by now. It's hard but we are making it and my son has everything he needs. Today I took a pregnancy test and it came back positive. I absolutely can not have another baby right now. We can't afford it and its not fair to my son. I never thought in my life I would be considering an abortion. I very much so believe that children are gifts but I cannot have another one right now, I can't see anything good about it, my mother would literally have a heart attack. I also can't consider adoption because there is no way I can carry my own child and give birth then just hand it over. I am so upset. I know we should have been more careful but I am just so beside myself. I know what the right thing to do is. But the right thing is going to ruin alot of people's lives including my son's.
