How to improve self esteem

Lately I've been feeling quiet "ugly " just not liking what I see. I dont real think about it often because well every day stuff gets in the way. But it really comes out when taking pictures or going somewhere i have to dress up. Then i have to look at myself. Yes i look at myself everyday but to seeing myself in pictures... i think why or how the hell my husband looks at me everyday. Ive gain weight more than i want. Im sitting at 180 with 5'4 frame. I look bloated how can i fix it. Ik gym and ive been going. Idk i guess im just thinking outloud tonight. Its late ladies, im sorry for making a rambling post...any ideas would be nice.
