How do I know that I'm not blocking everything, everyone good and missing out?

Someone said that the people that are meant to be your people will come to you. I liked the sound of this because it made me feel less anxious for about 10 minutes until I thought about all of the failed relationships and friendships with people in the past. I'm worried that these might have been 'my people', but because I am who I am, I am naturally just blocking any and everything good and missing out and 'my people'. I feel myself generalizing and that it might not be true, but it does feel true enough that I am worried and feeling like I'm sabtoging myself. I feel like I'm too this or not enought that that I won't ever be able to be myself and have 'my people' 'come to me'.
