I don’t know if this is a psychological thing or not, but I figured I would see if anyone else had this problem. I get unusually mad when anyone (and I do mean anyone) gets in my bed besides me. I also share a bathroom and get really mad if my sister puts any of her things on my side of the bathroom. I don’t get mad in a “my sister is annoying” way. It’s more like my brain starts going into overdrive and I want to scream. My entire family thinks it’s ridiculous and gets really offended that I start yelling if they even sit on my bed. Can’t say I really blame them. I feel awful for it, but I don’t know how to explain it when I don’t even know why I do it.
