Back to square one.....again :(

Well...I had lost about 22 lbs back around december and I have since gained it all back again. This is about the 50th time I have lost and regained the weight. I am so tired of this and can't quite figure out why I continue to put myself through this. I start doing really well and then let it all go down the drain and have to start over again and again. I just want for once to be able to get to my goal and maintain and not go through this roller coaster any more. I have never made it to maintentance and want it so bad. I was down to about 165 in January and now am back up to 188!... I stopped working out...ate ridiculously terrible for the last few months and now am paying for it. I have seriously thought about seeing some kind of therapist about my food and weight issues to try to figure out why I continue to put myself through this. I woke up this morning motivated and ready to tackle this again. Went to the gym and did an hour of zumba which I love and am back to eating healthy. The question is how long will it last. I am going to try my hardest to stay positive and stay on the right track. I have to do this. I have to.
