Hey dannyboi - I wish I could bottle up motivation and give it away for free - but the reality is, it can only come from within you. Losing weight, ultimately, is something you can only really do for yourself, not for someone else.
It sounds like you're just not ready to commit to losing weight and until that time, there will always be excuses or "reasons" why you can't get exercise (e.g. not in the "mood") or for example, why you have to eat a double helping or go for the junk food option instead of something healthy.
If you were committed to losing weight, you'd find a way to squeeze in exercise or find the money for a gym or personal trainer rather than spending that money on the road trips or junk food you don't need!
Exercise makes you feel good! Just commit to putting on your gym clothes and getting out the front door. I'm pretty sure you'd find yourself going for a walk, at least just around the block.
Small goals also help. Lots of small successes add up to a huge success overall. Try and think of one thing you can do tomorrow to set you on the right path - one small step, one small thing you can achieve success.
But anyway, anyou are here, and that is a good thing!
Sorry if this post comes off harsh, I'm just trying to put the boot in which is something i think you need right now
Just keep moving! And don't be lazy...
