I think I have trauma but I

I'm new on this app, I downloaded it because I feel so alone and horrible

I had a very toxic boyfriend, our relationship lasted two years. Last summer he sexually assaulted me, I screamed no and screamed stop but he wouldn't, like he was entitled to it or something :/, there was no consent, he did not rape me but he did sexual acts on me. He also has hit me before; once. It wasn't out of anger and hate towards me he just thought it was okay and funny, I bled a bit. i finally broke up with him for good in January and two months ago he told me he didn't love me anymore. I was very attached to him for a very long time and knew how toxic he was but I just couldn't let go. I've been having very vivid memories of those days and of the things he's done to me. If I see or hear his name I start to hyperventilate and end up having a breakdown which has been happening a lot lately, I have been hurt about these things for a long time but just now I have been starting to have panic attacks and breakdowns and started thinking about it more (not wanting to) honestly the things I mentioned were way worse than they seem, I am a very fragile girl and very hurt. Those two years were living hell for me. I am also very depressed and have been for a while because of him. So I'm not sure if I have trauma or not, it seems like I do but I don't want to self diagnose.

sorry for such a long text I just really needed to rant. Thank you <3
