I've read your post several times over the past week, feeling like I should chime in but unsure of how, so here it goes.
This sounds like you're dealing with a very difficult situation. I don't know how encouraging my input might be, but I can give advice (from my perspective, but YMMV). A situation like this, with one existing kid, no job, an ex who adamantly does not want a child, and an accidental pregnancy... it's a tough one.
For me, I've thought before about I would do if I got pregnant accidentally; I know that adding another child before I'd be able to support one would mean lowering the quality of life of my DD, so my choice in the situation of accidental pregnancy that I know I can't provide for would be to terminate the pregnancy or to go with adoption. For me (and again, this is probably different for different people), it would be morally problematic to make my existing child sacrifice her security and quality of life, to be unsure of being able to come up with rent and safe childcare. For me, I would also give some weight in the decision to the fact that the other person involved (the ex/the father) would be responsible for the next ~20 years for a pregnancy he doesn't want and didn't intend (I don't know how it works in your state, but in mine the state will sometimes aggressively go after absent fathers for child support if the mother applies for state assistance (food stamps, work-related daycare subsidy, medicaid, etc), even if the mother and father both agree that he won't be involved).
On the other hand, it's absolutely your choice. I understand the feeling of wanting another child (and also the surprise at an accidental pregnancy), though I would probably wait for a more positive situation. If you'd like to know more about my lived experiences and how I've come to that sort of decision, I'm willing to share.
Ultimately, I'm just another poster on a internet forum, and each of us has a different and valid way making choices and dealing with life, and my intent in this post wasn't to pressure or hassle you at all. I know that my input is probably not what you were hoping for, and my apologies if it was unwelcome, uncomfortable, insensitive. As for advice on job stuff, getting a job as a bank teller could work, which is full time (as opposed to retail, where I always found that I was never able to get a full time schedule) and has health insurance benefits for full time. For teller jobs, sometimes cash handling experience through retail is enough to make the jump from retail cashier to bank teller. I know that some people sell crafts on etsy as a SAHM gig, but I personally don't know much about that.
Anyway, that's my two cents.
