You mention control issues.
I’m not a control freak, but, I have developed an individuality aspect to my life, being so self reliant, I could not ask for help if I were gunshot in an alley.
In either case, trust is an issue.
Trust is very difficult to develop when you haven’t used any for a long time. However, for survival, trust is absolutely necessary at times. Knowing when is the big trick.
If you have ever seen the television show House, it is all about trust.
There is this brilliant diagnostician, and he never trusts the information patients give him, at least not initially. That is because he knows everyone has things about themselves they don’t want anyone to know, at the risk of death sometimes.
I got forced into trusting. I have fallen victim to a condition which leaves me deeply vulnerable, and forced to trust others to help me, to know things about me, to do things for me. This includes strangers frequently.
I hope you can find a way to develop some trust in others without being stricken as I have.
Perhaps you can make a game of it, like the show What Would You Do? Choose a situation as a test. Trust someone in some small way, with no direction from you at all.
Have a prediction thoroughly thought out. See if the outcome matches your prediction at all.
