Its more than a trim!!!

Hey Ladies, I have some terrible ends. My hair needs to be cut. I say cut and not trim cause i think about 1-2 inches need to come off. I'm so pissed right now at myself. Every time I look at me ends i get disgusted. Its my fault cause before i came to this site I got lazy with my hair and didn't moisturized or wore scarfs at night. On top of that I reached my next goal of BSL and now i have to start over. I think i would have reached MBL or close by my next relaxer in Sept. I am so pissed off right now. I'm going to trim my hair myself cause i don't trust anyone else in my head with scissors in their hands. Right now I'm trying to decide if its best to do it on wet or dry hair. Ladies what you think?
