Restraining order against ex girlfriend.

I am 18 my ex is 24 almost 25. When we first was together I was 17 years old and did not know what I was getting into, my friends advised not to be with her because of her history but i didn’t listen. I cheated by downloading the app grinder shortly after I turned 18 which i understand was wrong but she chose to forgive me. At the end of the relationship we would be arguing the whole time and she’d always try put me down. She ended up cheating on me with a random person from a club and was cheating on me with her best friend the whole time anyway. 2 months have past and I keep getting long messages encouraging me to commit suicide, trying to put me down all with homophobic remarks trying her hardest to put me down. I don’t reply and try to ignore it but these messages are pretty intense. She sends it from different numbers when I block her and yesterday she even hacked into my tiktok and deleted all my videos. I have all evidence and everything. What would you do in my situation
