What is your greatest weakness?
Let's unpack the list: I can be a procrastinator, I am lacking in self-confidence, I am not a good manager, I keep things bottled up, I dislike confrontation so much that I do a lot to avoid it at all costs, I am a loner and I think that this list pretty much says a lot. I can't think which is the greater weakness so that is why I listed a bunch.
Everyone is a work in progress and I am still under construction and renovation, I don't think that the word rehabilitation is necessary. Every year that passes, I hope to become a better person, more specifically a better version of myself.
I know my weaknesses and I don't mind working on them, I can't promise that I will cease procrastinating but being mindful of this flaw pushes me to do better.

You do seem to know yourself well through your posts.
It is good to acknowledge things and work on the things you want to change – and to accept the things you are happier living with.
