How and where to meet normal nice people?

[Oh Pickles]

I'm a female and just gave an exfriend a chance again after gossiping about me, my children, etc With intentions to do harm.. I gave her another chance and after 3 days of speaking to her I found.. she isn't going to change.

I don't know where to meet people, there is a group where women can get together and talk but.. it is a depression group and my above "friend" used to go there a lot.
I've tried on facebook.. but that is of no use.. no one likes me I think because I was "best" friends with person 1.

I feel quite lonely a lot..
Where can I meet normal people?
Normal = Don't think people are "watching them".
Nice = Isn't going to backstab me because I'm a size 6.
