Actually she isn't alcoholic anymore.
That's great. I'm happy for her.
get the forget out.
Ah, no. I'm not obliged to tell you that she's great and everything's fine because she's not and no it's not. She has a lack of self control and the inability to say no. It sucks she has depression but it's her fault she chose to have a drink at ~15/16 despite knowing what it could do to somebody who's mind is still developing.
Also, what kind of person goes and has a baby at 18 to "make her happy"? I guess that's fine-ish but still, that's just really dumb, considering you are a) not married to somebody who can help you raise it b) will probably have people raise it more than you will resulting in a disconnected parental bond and c) are putting another burden on others for your own "gain" (or whatever could possibly come out of this)
