Gave birth 4 months ago pregnant again

I have a bad situation to begin with, my kids are 7 years apart and my daughter is only 4 months older. The father and I have a bad/good relationship. What I mean is it’s bad the majority of the time but we also have a good time still. We can’t be together a d I just found out I’m pregnant again. It’s my fault, I’m not looking for sympathy I just need some support. I am terminating this pregnancy due to my personal situation and the fact that I just am not in the state to bring another baby into this world. I just can’t, my children now need me and I won’t be able to give 3 babies the best life possible and that’s not fair to them. Not to mention my epilepsy causes health issues for me while I’m pregnant and I’m allergic to the medication that is safe during pregnancy. Again I am just looking for support because this is something that will be difficult for me but I feel it’s the best decision for all.
