How have you successfully gotten over a breakup? I did not end the relationship and it was the most significant of my life. I feel confused and trying to understand why. I’m not sleeping well and my anxiety has decided to resurface. I’m ruminating. I don’t have many people to go to about this. Please don’t say I will find someone else, because I can’t go there right now. And I know it won’t happen anyway.
When a relationship ends, you’re watching something die. You will have to grieve, like you do for any death. Not just grieving for the end of the relationship, but grieving for all the lost opportunities.  The trips you haven’t taken together, things you haven’t said to each other, the family you never make together.
Unfortunately, it sucks.
These things take time to process, understand, learn from, and eventually move forward with.
You need to adjust to a new normal. And that new normal should be busy. Schedule regular gym visits, classes, language learning, book club, cooking, guitar time, whatever. Productive routine is important and it will help stabilize you.
Sometimes, the pain you feel will be greater than you built in resources for dealing with pain. This is when you add professional counseling to healing regiment. Please sing feel too proud for therapy. Even online therapy companies like BetterHelp are a great resource.
Go out of your comfort zone and say yes to being with people. Invited for after-work drinks, or a birthday party you don’t really care about… go anyways. You don’t have to talk to them about the breakup, just being around others will help you feel less alone.
Also, do a little house cleaning. Rearrange some furniture, get some new clothes, change the rug - something so what you see marks a clear before and a clear after. Take a vacation if you have some PTO and resources. You don’t have to spend any money or go anywhere. Just go to a park and chill on a bench. Relax a few minutes a day.
At a certain point, will be looking forward to tomorrows more than you look back at yesterdays. It could be weeks, months, but it’ll be a sign you’re ready to date.

This is such helpful information!
