I just finished a divorce a few months ago. During that period, my stress levels went through the roof, lost a job, lost a house, found a job, found a house, and now things are getting much better. However, the 60 pounds I had lost prior to ex going through mid-life crisis and putting the foot on the accelator (and ironically all of his mistresses have been very overweight and older than both of us!) have ended up putting 45 back.
Now, with a solid job for at least 16 months, a home to look forward to, just felt the time was right to lose again - and so far so good.
As for dating sights... I'm just staying away from them. The ex has gotten all his "sugar momma's" from them, and quite frankly, I have friends/relatives who honestly do know what I'm looking for in a man and are now setting me up on dates. I trust their "pre-screening" alot better than those dating sights and the double standards I've heard are in place with most folks. Looking forward to just going forward.
My advice, take a step back - there is a reason the weight came on, just like there was a reason it came off. Once you are solid with yourself, have the stress under control, you'll know the time is right to start the weight loss process, and nothing will sway the course.
BTW, My relatives tried to get me back on the program that was so successful with getting the weight off when they noticed the weight coming back on, but it didn't have a chance at that time... I was still battling the hurt from the betrayal, trying to find a job, trying to keep my home and keep things status quo for the kids since their father wouldn't.
It will get better... just have faith.
