<human>: EDIT: she was my first love/serious relationship and we were together for 3.5 years. We have been broke up for about 7 weeks (I'm not counting how long it's actually been) and had no contact for a month up until last night.

I know, I know. I shouldn't have broken no contact. And I know that relationships mentally end a long time before they actually end. But I feel like absolute shit.

I suspected she was dating this person a few weeks ago and she denied. We had a month of no contact when a friend relayed to me information that hinted she was seeing this person. Of course I get anxiety and have to know. It's confirmed she's seeing them and she says she never wants me in her life again.

Our relationship was horrible towards the end. I hadn't loved her for a long time and I think I just wanted things to work because of how the past used to be. I was doing so well dealing with the break up, but last night hit me like a ton of bricks. I feel anxious and sad and I don't even know what else.

I think the hardest part for me is just simply losing her. I never was good with having people walk out of my life. And I'm pretty sure the realization that we will never be a part of each other's lives hurts the most.

I don't know. I just feel weak and alone right now. I go back to college tomorrow and I'm not looking forward to it. I lost pretty much all my friends last year through drama and the only good friend I actually did have, transferred. I feel desperate and like I can't (and don't want to) carry on. I don't want to go to school, my anxiety is through the roof (I have an anxiety disorder and I'm on medication for it, but it's very bad right now) and I just don't want to feel like this anymore.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: ex is dating someone else and wants me out of her life for good. I feel desperate and don't have motivation to carry on with life.
