Im a college student abroad and was working and studying a lot this semester and I got dumped in my long distance relationship. Worst 2 weeks of my life followed, I slept 3 hours a day, couldnt move, didnt eat, missed my flight back, spent all money on new flight ticket and pcr tests and transport. I met up with her and got zero closure and she was rude and condescending and brushed me off. A lot of drama started as well and she and her best friend are seemingly trying to make me jealous on social medias and posting stuff targeted at me. She said she got bored and wants to live her life, and she's started to smoke a lot of weed and drink more than usual, which I didn't know only until after breakup. I dont smoke weed but I do love drinking, but this semester didnt bring about much party opportunities due to corona and restrictions. Did she get bored of me? Perhaps. For new years I cancelled a plan I wanted to do because of corona, and instead she and her friend are organizing a very illegal party to which my friends will probably go to (I said I wouldnt go, they probably invited me to make me jealous of my ex. Ive known her friend for a while and even from the start she wasnt completely supportive of me, and kept telling her to dump me or to get together with my friend, who actually liked her back, and always wants to start drama and make people jealous). I was even told that Im boring and should live my life more because I dont want to go to the party and risk a criminal record on top of corona risk for my entire family. I consider myself a fun guy but uni is uni, and if I work hard now I can play hard later. 

I wish I could just meet some other friends and get my mind off things but I cant do anything due to corona. All I can do is study for exams and have anxiety all day every day. These holidays were my worse yet. I keep making up scenarios. I used to be confident and happy with who I was, and really put my all into my degree, and now I'm left shattered. It sucks when you get dumped on out of nowhere, it came so unexpectedly and still I'm nowhere near recovering. Please advise.
