20 and divorced

So my husband just left me and now I have no idea what to do. I'm a stay at home mom and now I don't have my husband to support us. I don't have a job and I haven't had one since I was 17. Everyone wants people with experience to hire them and I have none. I can't make minimum wage because I have to support Aubrey and I. I am just so stressed and upset about having to leave Aubrey. I ball my eyes out every time I think about it. I'm more hurt that I have to leave Aubrey than joe leaving me. I just don't know what I'm supposed to do. I hate talking to people about my problems I never have been the type of person to do that. So I'm trying to work this all out on my own. It's so hard and I'm trying to make everything look normal so my family doesn't know which they do since he doesn't come home at night because I don't want to tell them until he gets all his stuff out of here. Ugh. This is not how it was supposed to be! If he was seriously still mad about the stuff I did over 2 years ago he shouldn't have married me and had a baby with me. God! I just wish he decided this sooner. Don't get me wrong I love Aubrey more than anything in this world but why would he have her and still be not happy with me. How could I not make him happy!!! I did everything for him. I just don't know what to do anymore. My self esteem is at an all time low and I just don't know what to do. Now I am a single mom with no job and no way to support my daughter and when I get a job I'm not going to have money for a baby sitter. I really hope my soon to be ex sister in law is still going to be nice to me. I don't need to lose any friends right now. And I still have people asking me for advice how can I do that when my life is falling apart. I still do though because I'm nice and I like to help. I just don't want her to end up like me. 20 and divorced. She is with a dead beat that she is preg by and I don't want her to follow after me. Don't be in a relationship you know if over. I have known for a while it was over just neither of us could accept it. Sometimes love just isn't enough.
