Struggling

I am 22 and have heavily struggled with depression/anxiety since I was young. At about 19-20ish I started being able to cope with the depression and anxiety a lot better. At the end of May, I got an abortion (through the pill form) and have been pretty consistently depressed about it. I know it was the right choice for me, but still feel guilty and hurt about the whole situation. Anyone have any tips to help ease the mental struggle?
