Is my friendship style a sign I might be autistic?

I am not diagnosed but I highly suspect I am on the spectrum, the signs I mimic other people’s way of reacting to certain situations, I used to think it was due to me lacking a personality lol; I take things literal sometimes for example, when I read my horoscope I know not all of it is true but at times I find myself abiding to it even if I know it’s far from being a science. But lately I’ve been thinking that I still feel like I have to be perfect when communicating with lifelong friends, I feel like I will disappoint or hurt them so I have to be extra careful? Don’t get me wrong I love my friends but I do feel like I have to behave a certain way around them, around people in general. Do you think this is a sign of being on the spectrum or could it be something else?
