Understand what you are saying and feel for you. Wouldn't take the time otherwise.

Do some reading on the subject of trying to leave the past in the past vs dealing with it. There are great books out there from people who are much smarter then myself and have spent their lives into understanding the brain and what needs to be dealt with vs what can be ignored. You will gain a better insight into yourself and others you meet.

You are still very young and have a lifetime of potential happiness ahead of you.
