Feelings of helplessness and not feeling good at anything, they can be a trigger to an eating disorder. You feel like you arent good enough, and its those thoughts you have to work with. For me, i know i had control issues and low self esteem so during recovery i had to work with those. I had to let go of my control and having to control everything as well as learning that actually i was good at things. That i wasnt awful, ugly and useless. Because that isnt the truth. And its not the truth for you either.
Along the way, whether it takes a few months or a few years, you will find what youwant to do. But you cant give up just because it seems hard or hopeless now. You just need to find what it is you want to do and what you love doing.
