My time in Europe is coming to an end tomorrow.

I spent a lot on my dad's card here. I know that was unavoidable. I feel really bad about how much I drank, but I had a hard time not getting wasted when everyone else was and when I couldn't just go home. Plus the beers are really strong here. Plus, I get nervous at social outings with people I don't know and that makes me want to drink more because I am comfortable and don't have to worry about my problems.

I got all As here and didn't do anything dumb to hurt myself, but I feel bad about how much I drank because I don't want to be that type of person. I'm working towards adapting my life in my near future so that I am able to live a life that has a healthier approach to alcohol.

What are some strategies to accept that the past is the past and the future is still able to be determined by me? How do I not beat myself up?

I would love any advice/words of encouragement. Thank you.
