I have trouble looking at myself, and I feel disgusted when people look at me. I'm considering dramatic change to my hair, would this possibly help?

I've never in my life dyed my hair or had it really short. Lately I've been wanting to, and thinking that maybe a dramatic change would help me feel better about myself. I'd like to get it dyed an unnatural color, and cut sort of like a messy bob cut.

Would this be a disaster?
