How should i try to make friends?

I've made friends in the past, but they never really treated me like a real friend. They treated me as a lesser being. In a way like i was nothing, like my opinion didn't matter. She always tried to invalidate me, and make me feel worse so she could feel better. Whenever i talked back to her she wouldn't talked to me for months. She would make all my "friends" hate me and talk behind me so i could hear them. After time, and time again she always came back. Over time she started to loose friends, but I was always there, and i always forgave her. After all that i was her only friend left. She isolated me when she lost all her friends so i couldn't make any. It's been two months since i decided to cut her off from my life. When i did that i felt amazing. like a weight had been lifted, but now i feel empty. I'm not quite sure how i should make friends anymore. Can anyone help? (●'◡'●)ﾉ
