Hi Tisha,
Welcome, I'm new too and just getting started. I don't know, but it might help to put some thought into why you're quitting when it's working? It's almost like you're self sabotaging?
It took forever for me but I finally figured out that I gained most of my excess weight after a couple of bad break ups and realized that I was hiding. It's easy to avoid a relationship, and thus a heartbreak, when you're fat. Despite thinking that I wanted/needed another relationship, I realize now that I wasn't ready for one and wasn't in a healthy place (emotionally) so subconsciously I was protecting myself from the possibility of one. I still don't feel ready for a relationship or really even want one at this point, but I've come to realize what I've done to myself and the consequences of what I have done, and it's not what I want anymore. I want to feel good about myself (all of myself) and I've made a commitment to myself that I won't get in a relationship until I feel ready, but that I need to go about that in a different way.
The point of all that rambling was that I was sabotaging my previous efforts at even considering losing weight because a) I didn't believe in myself but more importantly b) I was protecting myself. So maybe you're doing something similar but with a different reason? It just seems odd that you would quit during success, ya know?
Anyways, again welcome and I wish you success
