It took a long time and I went through a very dark period. In fact, I barely survived that time of my life. But I did eventually come to accept who I am and be comfortable with it.

I pretty much accept all parts of my life and past except for those things I actively work towards changing. I know my social skills need a lot of work and so, I don't just accept my poor social skills and move on, I try to make progress in that area. Likewise I have money management and laziness issues that are part of my personality but that I actively work towards changing. I think that accepting who we are is not the same as accepting that we can't change. Like the AA creed says, the trick is in figuring out which things you can change and which you can't.
