What do I do?

About 2 years ago I went into a deep depression and gained 50 pounds. I have lost weight since then and I feel better about myself but my love handles really bother me. The only thing really big on me is my muffin top it’s really not that bad in my stomach part in the front but on my sides my love handles are big. What causes love handles to be that big and how can I get rid of them?
