Couple of blending in tricks. Look people in the eyes and learn to greet people at work as they see you. Simple hi or hello. Those two things did wonders for me.

Had a boss tell me I never look people in the eyes and it makes them feel unimportant or as if I feel I am above them. He said it dampened my personality for people. Made it harder for people to get to know me. I took that to heart and started making sure I looked people in the eyes more. Helped a lot.

My partner also told me I never really greet people or say hello. When I pass people at work or meet up new people I just don't even say anything. It makes it really hard to start a conversation with me. So I started just saying hello to people at work in passing. Accidentally made a few friends.

Like you I felt I always had bad work environments because people seemed to not like me everywhere I went. Didn't know what I was doing wrong. I was quiet and did my work and went home. People want to be recognized and feel like they matter. You're unfortunately a part of that game at work. To be honest though it's not so bad. It feels good to make someone laugh at a joke or smile just because you said hi and no one else recognized them that morning. Those two simple things really turned my work around. I don't feel like everyone at my work hates me. Even opposite I get along well with everyone and I can be pretty honest about being antisocial. I'll hang out with people sometimes but when I don't feel like it I literally say exactly that. Don't feel like it. Just wanna be anti social and they just laugh at it. They're cool with it. People are accepting if you take a small step to make them feel accepted to. Even if people don't say it they want your acceptance or else they will disregard you as a person.
