Lose weight!!!!!!!! Help please....

I'm a newly wed, I've taking pills for birth control. When I got married I was 128 pounds and I'm 150 pounds I'm so depressed. Not to mention people have noticed my weight change. I've jogging to lose more weight and eating healthy. I don't know what to do.  I feel helpless I've never thought so highly of my self or ever been conceited or full of self. I just want to feel better. Pleasee any suggestions I will appreciate a lot.
