I've been there. And back there again. and again for most of my life. It seems to me that if you aren't completely succesful at losing weight the first time around then it gets harder and harder to cling on to hope. But you know that doesn't apply to everyone.
for me motivation is keep the light at the end of the tunnel in sight. When things get tough just think about say your wedding for example. How will you feel on the day if you haven't lost weight, or have even gained. vs how you would feel if you lost 30lbs. Keep your reason for wanting to lose weight in the front of your mind.
It helps to have people to talk to about it. That can really relate. Going back to the light at the end of the tunnel, it can be exhausting running through it alone but running with others can make it fun and often entertaining.
how is counting calories and exercising a short cut? if thats what you mean...
Someone on this forum said to me recently, fake it till you make it. And it's true. Keep going the motivation WILL follow. if you do it right you will lose more and more and thats all the motivation you'll need.
Good luck with it and welcome
