Hello people!! Please No haters cause I do enough on hatin myself!!! A year or so back I started my fitness pal and I did great I went from almost 180 to 145 then holidays and laziness came so I gained a bit of weight back UUmmm round 153 or so I believe I gt upset with myself N started coming back I was not losing but maintain that time then summer came and I have 3 kids and babysit lots of others so of course I started eating what they eat and not working out now I'm 160 and Pissed at myself I know I can do better I just find excuses to NOT cause its hard and I don't really have any support my husband and boys have a natural I'm skinny gene!! They are not against it or make it hard for me but.... its something I have to do alone I guess that's my biggest excuse!!! Anyway Id really like some motivators if U don't mind.. Maybe Hopefully I can Stop thinkin about not wanting to do it alone and start thinking if I want it I gotta fight for it!!!!
