New, Excited & looking for friends to help this journey!

Hey y'all!! I'm here for some new girl friends and some encouragement!! I usually keep to myself about working out and eating right but I feel every time I try I do good for a week or so then I fall off the band wagon! I'm 5'0 and weigh 123.. I'm trying to get my weight down to 100.. I know it sounds crazy but that was my best looking weight!! Ahhhhh!!! So hopefully with some encouraging and actually doing what I am supposed to I can finally get there again!! Yay exercise and eating right!!
