I felt like an alien too and I still do. I was just gradually becoming myself more and more. I was facing my real self and my real desires and that is how I attracted real friends. I carried a lot of shame inside for being myself, but then I decided to stop running away from myself and let myself be me even if I am perceived as weird. It will be awkward and unpleasant at times, but honesty with yourself and others in the right contexts will pay off immensely to you. When I operated on a lower lever of my consciousness, relying only on my social mask, I wasn't able to find real people to connect with, but only those who reflected my mask, ie fake ones. But sometimes, you can find yourself surrounded with people who are not like you on a daily basis without your choice. For example, in high school, so maybe try to find some activities or different places to hang out with people who are more like you.
