hi everyone

I'm not sure if anyone will actually see this but I'll still give it a go.
I was wondering if anyone could maybe give me some advice on settling in at uni both in terms of the social side and work load from my course.
I've found after getting through the first semester of first year I'm not really where I thought I would be with my progression with new friendships and coursework.
I'm on an art based course, and i went straight to uni after finishing my a levels. after sixth form I felt extremely burnt out and I took the summer holiday to recover and even took a break from doing any art at all (I was so tired after finishing my a level graphic communications). i went into uni feeling refreshed and determined, however I found that pretty much straight away I began to feel burnt out again. throughout the semester my course has flown through 5 heavy projects alongside prep for an essay (in total im in about 16 hours a week). over the Christmas holiday I have to write said essay, complete another project and put together a portfolio of all my work completed so far for an assessment.
compared to my other friends from back home who are taking non-art courses, I have a decent amount more work. I was told by a lot of adults in my life that university was great and first year would be quite chill and relaxed, but I've found it to be the complete opposite. I feel like I'm barely able to keep up with the work while other people on my course are completing it to a much better quality and are even doing other artwork outside of the course. and everyone is so incredibly talented, sometimes I get really demotivated and feel like I don't belong there.
I also feel like I've not done particularly well with the social side of university either. I really struggled with social anxiety in the past and I spent all my school years being quiet and reserved, only talking to my close friends. I had people tell me that when I went to uni I could "reinvent" myself and be whoever I want to be, put up whatever front I wanted to. and I really tried that at first, I tried to be this funny, confident, unbothered person i always wanted to be in school, but I just couldn't keep it up. I felt like I wasn't being myself and I was really uncomfortable. so I decided to just be my true self, but I just I feel like I'm always awkward and I dont feel comfortable or settled down with anyone. like I get on with my flatmates and I have coursemates I talk to and see outside of class occasionally, but whenever I socialise I feel like there's this bubble/barrier around me, and I can't quite let my guard down and be myself because I'm so scared of people not liking me and finding me weird.
since coming home for the holidays I've talked to my friends from home, and a lot of them feel like they can be their true self more at uni. they are happy and have made some close friends there and have free time to read and watch tv and enjoy their life. whereas I'm either constantly doing working, forcing myself to socialise to strengthen bonds with people or doom scrolling on my phone because im exhausted.
I just can't tell if this is normal or at least if this is a normal experience for some people during their first semester, and if it gets better. is it a time management problem? Will I feel more close to people after coming back for the second semester? is there anything I can do to stop feeling so inferior to everyone on my course? I really don't want to consider dropping out as I just know I'd sit around at home doing nothing all day :/
any advice on any aspect of this post would be greatly appreciated
thank you so much!
