Hi! I'm new here, but I just wanted you to know that I really relate to how you feel. I've sort of felt that way on and off my whole life, actually, because I've always been asking those kinds of questions (I was raised in a home with a lot of chaos, and it was develop awful habits or find some meaning and survive -- I chose to find meaning).
Anyway, as I've grown older and matured in my thinking a bit, I've realize that many of the people I had surrounded myself with were not the right people for me any more. I've heard wise people say that sometimes we outgrow friendships, and maybe this is what's happening to you. You've come into a new way of thinking about the world, and now you need to meet other people who are on the same page.
It gets lonely when you do not have a place to express yourself, or someone to hear your, or someone to see the world at the same depth. So yes! I'd say you need a little support. And I think the more you learn about yourself and what makes sense to you, the more confidence you'll have to go out into the world and find like-minded people, or at least people who are on the path.
I really should clarify what I mean by like-minded people. I don't mean that you should find someone who thinks exactly like you, but rather, people with similar values and goals. I.E., people who value personal growth. For me to call someone a close friend now, they must be self-aware. So I seek out people who are. I find many of them online, but also find them in meet-ups and community activities centered around my recreational interests and spiritual beliefs.
It's normal to feel like an alien for a bit, but there ARE other people out there who can and WILL see you and see what you see, and eventually you will find them. HUGS!
