I'm sorry to hear you're feeling this way, the important thing is that you've discovered this early and are trying to do something about it. I remember having a similar situation in second year with people not turning up for group projects so I pretty much just went to my lecturer in a private meeting and asked about it. They said that when it comes to grading, they've become familiar with each student's work by this point and they can tell how much work each individual has put in. They also said that although attendance isn't counted towards the final grade, they can make a correlation between how much the person had turned up and the quality of the group project because at the end of the day you all get individual grades. As long as you make your lecturer aware of what's going on then they should take that into consideration.
In terms of moving universities, you could enquire and see what the entry requirements are of the place you want to go. Id recommend doing this sooner rather than later but I wouldn't want other people not turning up to be the reason you'd start again because at the end of the day the degree is for you and no one else, you're responsible for your own outcome. If you enjoy what you do then that's what's important. I'm not saying stick it out because if you're unhappy then you're unhappy but it's important to remember that there's a reason you picked it in the first place. There's going to be modules in every year of study that you don't like, there is in my course and I just do them because i enjoy the rest of what I'm doing. At the end of the day no one can make the decision for you but yourself. If you'd like to look at switching then I'd recommend putting the plan in motion to make sure it's all sorted for next year.
Hope this helped!
