I have many, many regrets, my life is a case of "Don't really know what you have until it's gone". I wish I could use a time machine and right all the wrongs, but life gives no second chances. My biggest regret is that I didn't take good care of my health, and ignored all early warnings and signs... and it's coming back to bite me in the *** now.

I can relate to almost everything you said too, not standing up for myself, drinking, not moving out, lashing out at family members and more.
