I have many lifelong friends who are effectively 'kin' aka almost extended family and I don't drop friends because sometimes they might grind a bit, or as we age we see some things (very) differently. Frankly, some of them are a bit odd and have very few friends of their own - they're not going to be 'ejected' because they are not always in support of my sanity.
I don't keep 'fairweather friends' who suit my current lifestyle, mood and social status.
I enjoy the company of my work colleagues a lot, it's friendly without having to be too intense, and we can talk about 'work stuff' which I enjoy.
So you might also want to contemplate a different definition of 'friendship'.
I know I came off very cheeky but your statement "forced to behave", indicates that some people in your life do not behave well around you. I think it'd behoove you to consider whether those "friends" are using you, in a nefarious manner, or whether they perhaps do not deserve your attention.
