TeenHelp - Work dilemma.

So I have two jobs - one of them is a Monday-Friday full-time childcare role and the other is a weekend position at a bar.
My dream career is ultimately to be a teacher which I am currently studying my education degree.
Basically, the only reason why I work at the bar is to get some extra money. The management and other staff are great and I get along with them all. The problem is the job itself. I used to love working in a bar and a part of me still does to some extend. But it's starting to affect my mental health more than what I thought it would. Back in December, there was one particular night that was quite rough for me. Essentially there were a lot of customers that were intoxicated that night and there was problem after problem that the majority, if not all of the time, I had to deal with and handle. The assistant manager I felt like was just hiding upstairs in the office. Since then, I found that I have grown increasingly anxious especially during my evening shifts due to my fear of a patron being so intoxicated that they may fall down and hurt themselves because I served them too much. I know they are adults and they are accountable for their own actions but I still feel like it would be my fault if something happened. I've been working at a bar for the last four years and nothing like this has happened but I just can't get it out of my head.
Today, I have been offered a tutoring job which I most likely would take to do after work and over the weekend but there's so many thoughts running through my head. The pros of taking this tutoring job is that it's closer to where I live, it will help me in the long run with my career and it pays more an hour. I will also get my social life back because I won't have to work Friday and Saturday nights anymore. However, the cons will be the possibility of not liking the position or not being good at it which is like taking up any other job. If I would take the tutoring job, I would resign from the bar job and possibly only work Sundays during the day so I won't have to deal with the drunks over the weekend.
I'm just all over the place at the moment.
