Should I move away for uni?

I don't really know how reddit works but I'm going to try anyway cause I'd love some help. I'm 21, super anxious and have no friends. My family are amazing and are my support system. I haven't always been this way, I used to have lots of friends and a social life when I was a teen but then covid happened and I lost all of that and became extremely anxious. I went back to school at 19 to be able to go to uni and I've been thinking recently about moving away from home for university because I know I need to do something for my life to change. In addition to this, I live in a smallish country with limited universities/courses, and in general not a lot to do. I feel like im wasting my 20s and want the university experience. I'm just scared that i'll move away and have no friends because im awkward/shy and will feel lonely and anxious. I'm also worried about being 21 (turning 22 shortly after I start in September) and being isolated cause I'll be a "mature student". I just want friends and to have fun but I have no idea if this is the right thing to do. I guess I'm just wondering if anyone has had a similar experience and could give me any advice? I would be extremely grateful 🙏
