Feeling so lonely.....advice? Please, please read. Need some help ladies.

First let me say that I'm 34. I moved down to Florida 3 years ago. Left everything I knew behind (bc of divorce) I wanted a new start. I lived with my best friend for a while until moving out with a girl I had met. Well fast forward to now.....I live alone with my dog. Have basically no friends. The only people I see are my best friend (but she has a husband and 2 kids) and my newest friend who I've become pretty close with. She now has a new boyfriend. So here I am again left in the dark. My whole family is still in NJ. I do love it down here but I don't know why I can't make friends. My insecurities tell me its because I'm too fat. And that's also the reason I'm still single after 2 years of trying to date. Any ideas on how to try to make new friends? I can't in my job bc I work for a private family and have no coworkers. If you made it this far, thank you for reading. I cry over this quite often. No backyard parties or girls night out for me. Ever. I hate going on fb and ig bc I see everyone else having fun with their "besties" and I'm always alone. And hate myself in pictures. Any positive advice for me?
