*hugs* I find regret hard too. I don't know your full story, so please forgive me and ignore this if it doesn't make sense... but here's some of how I deal with regret...

First, I look back at the situation and try to determine if I made the best decisions that I could, given the information that I had. Sometimes, for me, what I really regret is the *outcome*, but not necessarily my own actions. My actions may have led to a bad outcome, but in that moment, if there was no way that I could have known or expected that, then I can't really blame myself. (Another way that I look at it is, would I do the same thing today, IF I had the same information as I had then - not the info that I have now about how things turned out!)

- If there was something that I wish I had paid more attention to or done differently, I try to take that as a learning point for the future. Right now, with my last T dumping me, I look back at the red flags and wish I had noticed them much earlier. So, I'm thinking through what those were, why I ignored them, and what I should do differently in the future. While I can still regret what happened, this helps me feel a little better, because it feels like I'm learning from my mistakes so that I don't repeat them.

- If part of your regret is judging yourself, think about how you would react to a friend who did the same thing. Often, we judge ourselves more harshly than we would a friend... so try to remember, everybody makes mistakes (and it's normal/human! We can't be perfect, can't know everything, etc.) and be kind/forgive yourself.

Not sure if these apply for your situation, but that's what tends to help me.

*hugs* hope things get better soon!
