I'm under a lot of stress and pressure from my last year in college so I've devised a plan to just lose when I lose. I've stopped all goal weights and targets that I had set monthly. Now I'm just eating as best as I can, like always and getting a little bit of exercise in when I can. If I don't get any exercise in, I don't feel bad now. Sometimes there are more important things in life than a diet plan. At first I struggled to find the motivation to get back on track after I went back to college in September but finally at the end of October I was able to become motivated to try get back on track. I think it could have been down to changing up my plan and just losing when I lose.
In order to get yourself motivated, it takes different people different things. For yourself, I would think of your upcoming wedding. You don't want to look a certain way in your pictures. (Although I'm sure you will look stunning regardless of what weight you are!

) You don't want to only be able to pick a couple of photo's to show your friends. Think about these points that
you are telling yourself and maybe reorganise your plan to something more manageable.
I went from around an hour and a half of exercise during the summer to a plan of 30 minutes on the weekdays and an hour on the weekends. Granted, some days I don't get the full time in. But like I explained, I don't feel guilty because 30 minutes is better than nothing. Heck! Even 10 or 15 minutes is better than nothing.
I was talking to a friend of mine last week about this and she was making a photo album for a friend of ours. There was a picture of me about two years ago when I would have been my highest weight of 154lbs. I thought it was the most disgusting picture of myself ever! But my friend told me not to see it like that but as motivation to keep on going! She suggested sticking it on the fridge.

I didn't do it but I thought it was a good suggestion to get some motivation. And if I feel like I'm slipping, I might just have to look at pictures of me a year or two ago and see how far I've come.
