Hardest decision of my life.. **may be a trigger for some**

Okay ladies so I have been struggling with depression and anxiety for a couple years and it kind of heightened after having my son who is 10 months old now.. just a couple of weeks ago I was in an outpatient program at a behavioral center and was diagnosed with anxiety and depression and was given a prescription for Zoloft.. three days after that, I found out I was pregnant. I knew that I always wanted my children to be close in age but I just don’t feel like now is the right time for me to have another baby... my sons father and I do not have the best relationship and we are constantly going back and forth.. (*hence me getting pregnant and we aren’t even together)* I used to live with him but I moved back in with my mom like 4 months ago because we were just arguing way too much.. I don’t have a job rn because I’m the sole caretaker for my son... his dad sends money for things that he needs like diapers etc but I am with him 24/7 so as of now, I don’t have a job and if I stay pregnant than I probably wont get one for a while.. when I was younger, I always always always told myself that I would never get an abortion (only because that’s how I personally felt not anything against anyone who has). My older sister had an abortion when I was very young and she stayed in bed for days just crying and I never felt like I could do that... but now, being 20 with an almost 1 year old and having intense anxiety and depression, some days I feel like that might be a better option.... but then some days I’m disgusted with even having the thought cross my mind... I feel like if I go through with this, I may never forgive myself.. but if I don’t, and I can’t get my life together, then I will never forgive myself for that either.. I just need some advice on what you ladies think I should do, or what you would do.. I am 7 weeks now and I need to decide soon but I just can’t bring myself to do it.. I can’t talk to my sons dad about this because he doesn’t understand things like me taking medication because ******depression is a sickness******.... and I know for 100% that he will not understand that I genuinely just don’t want to bring another baby into the world right now when I don’t have my shit together..
