You can't fail unless you allow yourself to.
Baby steps but jumping right into it is good as well.
Maybe have a cheat meal once a week (It helped me in the beginning and sometimes now especially on binge days.)
Mini goals are always good, so every 10 pounds reward yourself?
When shopping stay on the outside, because all the processed food and junk is in the middle ailse.
Log on here often for support, and get support from family and friends.
Also congrats on the two pounds you've lost already! You can do this, you want it and failing is not an option, because in the end we were always taught to fight for what we want right?
Good luck!
