I blame my mother for my eating disorder
So, what exactly makes you blame your mother for this disorder of yours?
From the age of 2 and beyond, my mother started calling me fat and other related insults.
That is awful on her part, I agree. You're an adult now, though. You should recognize it's not right to blame others for your current issues.
I think if I talk with someone about this, I'll begin to heal.
Yes, you will heal and it is important to talk about things that have brought you distress. Eventually you will be able to think about it without it owning your mind, and that will be a great day for you!
