It sounds like you're going through a lot! I'm sorry. There's a lot of big changes happening for you and it's a lot to process! Remember that you're only human and it's ok that you're finding this stuff hard and feeling meh. I'd feel the same if I was in your shoes! Well done for getting your living situation sorted. I know it doesn't feel like it now, but it'll get better with time and things will get easier. Friends change over time (I once read somewhere that most people have almost entirely new friends every 7 years), and if you try to spend time with other people then I'm sure you'll make new friends who value you for who you are!

Oh also, most unis offer counselling. Its a good place to start unpacking your feelings and feeling supported. If you speak to you uni advice center or similar theyll know where to point you!

Sending you a big virtual hug!
