Welcome! I'm not trying to be mean or anything...BUT...
What would going to the bar to spend the little $$ you have on booze solve? Sure as hell isn't going to make your mother think any better of you and even worse...How will YOU feel afterwards? Why not instead;write out a sobriety plan. Stick to that for a month,then write out a 'professional'(work) plan..Then; next goals(housing,ect.).Drinking solves NOTHING and only gets worse. You're still young enough to get ahead of this 'thing' if you stay sober and that will allow you to lead a great life. Sitting around and sulking that your mother is upset will get you nowhere. That's on you. Get to it!
