New here!!!

I have tried so many different ways and nothing sticks. Recently I even got a personal trainer and that was big flop. I had always wanted to get a personal trainer but could not take on the expense and for my birthday that was my present to myself. I was recommended to this guy that owned a gym about 20 minutes away. I did 8 sessions with him and it was a joke. He was always late and always cut our sessions short. He never did a weigh in and measured inches. The diet plan was a joke, so coming from no plan to what a body builder eats is crazy. I came to find out that he was more interested in his clients that did Body Building. Anyways losing weight is something that I think about 24/7. I am so self conscious of the way that I look. Any advice, help or support is always welcomed here!
