Hi Showmesomelove, tricky situation you're in. To be honest, there are solutions for most problems. Sure, they can sometimes be so complex and difficult that it seems like there's no answer.....but with courage and determination you can find a way forward.
And sometimes the answer is to just learn to accept that there are some things will cannot change. If that's the case, it's about finding peace with the the way things are.
All that being said, there's a limit to what we can offer without a story from you.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
