Have you considered talking to a therapist?
hole in the ground
Now that you've stumbled upon this hole, drop some random thoughts, vents, test posts, or anything that does not break instance rules. I hate moderating, don't make me work.
Go read the book "the power of now by Eckhart Tolle" and try to be open-minded when reading it.
I know it's spirituality stuff which many frown upon (myself included at first) but the way I look at life now has changed so much (for the better obviously)
Reading it you will realize that the past is already gone. It's just a part of you that you don't want to let go because you are afraid of losing something that defines you. But in actuality it is not what or who you are.
I really hope you can give yourself the push of reading it. Even if everything it says doesn't align with you, what are you losing by at least trying?
