Finally ready to get this weight off

Hi,
I am finally at a point where I have the right mindset to lose weight. I got out of the military 3 and a 1/2 years ago to take of my mother and got through an amicable divorce. My mother passed in Oct 2012 and I have taken over the care of my autistic brother. So that left me a divorced mother of one and the sole provider of my younger brother. I have slowly gained 65 lbs. I have no problem exercising. My problem is not eating enough and when I do eat clean I seems impossible to get to my calorie goals. I hate forcing myself to eat when I'm not hungry. Any tips, advice, or suggestions will be greatly appreciated. I would also like to meet some new weight loss friends.

Thanks in advance
