I just don’t get it.

I have probably over thought stuff. However, I am still trying to understand how neurotypicals work. I don’t know how they can pretend when it comes to how they feel. I messed up big time but it is like my friend had no feelings toward me after I saw the video on the TikTok fyp referring to me. I thought we were getting to know each other and felt caring toward each other over the last couple of months??? I thought that I at least meant a little to them. I keep racking my brains (doesn’t take long because I am simple as two planks) and I just can’t understand. It upsets me when I think that they meant something to me and I meant absolutely nothing to them.
