I have tried again and again to lose weight, but I have terrible will power, I manage 2-3 weeks at a push. And even if things are going good, I start to get tired and sad. And then I start allowing myself to give into the excuses in my head. I'm tired, I need more food and sugary food to give me energy. I'm tired after work and instead of doing my exercise video, and having dinner and a shower, I just go straight to bed and read a book. I feel that if I don't indulge myself in dinner and 2-3 hours awake after work and go straight to bed. Then it's ok to skip out the exercise video. Right now I'm in a slump, I know I've been bad this week, and instead if wanting to try and climb out of the whole and get back to the challenge. I just want to wallow, cry and hate myself, because I know if I don't lose weight, I won't let myself buy new trainers, or a pretty dress. Has anyone else found any good tips to get themselves out of the wallowing pit?
