You're not working to exist.
Don't change. I've had a workplace where I've fitted like a glove, loved the job and then been told on a drunken Christmas work night out that I didn't really fit at first but they all 'grew to like me�, which came as a shock as I thought that they'd like me from the start.
Then I've had the job where I felt so out of place I wanted to quit and, when I actually left, at my leaving do was honestly surprised by how many people were upset that I was leaving - including managers.
You just make friends as you go along. Make sure you keep the people you like in your life even just by saying 'Hi' by text or something daft every now and then.
Just be you.
