feeling guilty and depressed after breakup?

What's done is done. Get up dust your shoulder off and move on. Bigger and better things awaits you

While there's a lot we folks here don't know, feelings of doubt, guilt and sadness are normal after a relationship ends. It's natural that you feel bad for hurting them - you cared about them. It's important to remember though that while it may not be immediately obvious, chances are, your partner is strong. And your partner will get over you if they haven't already. Again, it's natural to feel guilty.

I have been on the other end of a long relationship break up. Odds are, given that they were with you for so long, they care enough about you to not want you to stay in the relationship if you're not happy with it.

Don't overvalue yourself. That's a big part of that guilt you're feeling. People move on.

I got broken up before I boarded a plane to see my ex. She bought the plane ticket. It fucked me up big time. I couldn’t get up my bed for about 6 hours after I woke up. It messed me up building my startup. It’s been about a year.

Hurt them? How many were there?

Not sure how she feels. But for the first time of my life I felt physical pain seeing someone and nearly would pass out.

FYI

Like firing someone who is underperforming, it’s in their interest to end the situation as quickly and cleanly as possible.
