What is this feeling so sudden and new?

So just to be brief because I haven't been home longer than 5 minutes since 5:45 this morning. I am just going to state what is really on my mind and honestly it's friendship. There are so many different types of friendships in this world and I am not about to lie, I have been contemplating what type of friendship I truly have with certain people. It's hard to say but, a small part of me is wanting to scream out "that is not a true friendship at all" and then I feel bad for thinking that but everyonce in a while something happens or a thought process emerges and I find myself at square one all over again on what type of friendship this truthfully is. And no, in no way am I going to state the name of said individual, and in no way should you automatically assume it is you. In the right way at the right time, if the information with said individual needs to be shared it will. It just throws me for a loop sometimes, and I could be making something out of nothing, however I am none too sure.
