Over the last few years I have put on 3.5 stone. I have tried different things to lose weight, joined slimming world, gym, tried diets at home but I just can't stick to them. Am so depressed about how I look that I don't want yo go.out or let DP see me with no clothes on but just can not stick to any thing. Sweet tooth and busy lifestyle also to blame. Help what can I do? This is ruining my life.
