I’m sorry you have these feelings. Please seek the help of a mental health professional immediately. What is your goal with this post? I don’t think you will find anyone here who agrees that people don’t like you, feel sorry for you, and hate you. Your words indicate that you need more help than people on this site can give you.
Have a look at the linked posts, which might encourage you.

I don’t think this is a problem with UVA. I strongly suggest you make an appointment with the college counseling center, and/or a mental health professional. You seem to need a lot of support. I doubt people ask you to meetup because they feel sorry for you. If that was true, they’d probably just not bother. Please be proactive and take action to improve your mental health. You will need a more positive outlook whether you are at UVA or elsewhere. Good luck.
