Drinking while having a child.

The “vent” tag isn’t optional here but that’s what I’m trying to do. I drink about 4 nights of the week. I have a 9 month old baby. I’m still a good mom. I give him so much attention and time.. In fact I think that’s why I want to drink at the end of the day, because I feel so consumed with the baby time.. I need me time. I have a lot of anxiety and I seemingly can only express myself through alcohol. Are there any other moms here who drink? Anyone who can give me some advice?
