Hi, i think you could use EFT to get rid of those limiting beliefs, try also Doing TAT, for more info visit
EFT Provides Impressive Health and Emotional Freedom--New Discovery Often Works Where Nothing Else and for some videos go to
Tapping.com - Free EFT Videos - Emotional Freedom Technique, dont be decieved by how weird and ridiculous it looks, it still works and it helped lots of people.
You could try EFT with phrases like "even though i am weak to do things by myself, i deeply and completely accept myself.", "even though i feel like a child, i deeply and completely accept myself", focus on the feelings you get when you think about your problem.
Do you have no goals in life, a dream maybe?, i have a couple of dreams, i want to be an artist, a painter, i want to play the electric guitar, i want to make video games, i want to be a great person, those are goals, maybe you have some too, or, try searching in Steve Pavlinas blogs for help on how to find life purpose or goals.
Good luck.
