desperately need advice.

I just found out I'm 4 weeks pregnant. I already have a 3 almost 4 year old. me and my boyfriend just got our own house together. my first home that I've ever had. I'm just now getting my life together. We make literally JUST enough money to keep our bills paid, have what we need and have a tiny bit of wiggle room. if I have this baby I will be out of work. I make more money than my boyfriend. without my income we will lose everything we have. We can't afford child care and there is nobody on either side of our families that would even consider babysitting for me even if a paid them. both of our families are pretty shitty. my son is baby sat by his grandma on his dad's side of the family so that I can work. (my boyfriend isn't my son's dad, we split up) so with all of that being said, I honestly and truley think that if I have this baby I will lose everything I have worked so hard or. I won't be able to pay my bills, I won't be able to work, I won't be able to take care of them. I just won't. I need to be able to work. And I can't work with another kid. We just simply can't afford it unless we have a free babysitter which I know is not at all going to happen. I don't know what to do. if he made enough money for me to stay home I would be so happy and he said he would work 2 jobs if he had to but I just don't think we could do it even if he did. please help guys. our rent is the cheapest we could find, we don't have cable or internet. it's nor like we are just living the life and I would rather spend my money else where, we just really couldn't afford it working where we work now. without my income my boyfriend can not pay the bills alone whatsoever. I'm a waitress and he makes 10 an hour. I'm very against getting rid of babies for your own wants/needs. but I'm scared if I have the baby it won't have the best life that I feel I should/could offer. the only way would be if he worked 2 jobs and was never home with us. And I could start looking for something online but I have no degree and didn't graduate. if you guys have an suggestions please let me know.
