You're tired of doing it all on your own.
Being hyper independant is how you protect yourself. It's also a big part of why you're successful (Healing this doesn't mean you lose the parts of you that created success. It allows you to open yourself up to greater success).
You learned that you can't count on others.
To protect yourself from the disappointment & all the extra work it creates when you depend on someone and they flake on you, you've decided you'll just do it all yourself!
You justify it by convincing yourself it's easier. It's also exhausting & infuriating.
You don't have to do it all on your own anymore.
Imagine how much easier things will be when you actually start getting the help you wish you had.
