That's definitely a good idea, it seems like you don't really know why it's happening. A good psychologist should be able to get to the bottom of it. I hope it's free where you live as there are many bad psychologists that have no idea what they're talking about. I hope you don't have to deal with one. But, you could maybe check to see if they're any good by googling their names and reading the reviews, if there are any.
Just a quick background. Come from a broken family. Was on medication for depression and anxiety for around a year and now it's been more than 2 years that i have been off them.
So anyway, my sister who is not very nice with me says that I am a difficult person to live with but I've never taken it seriously because I have been told by her to die and she has been physically violent with me too so I don't think about it much however recently I've noticed that I don't like to make changes where I have a choice. I don't like people in my room going through my stuff or trying to clean around stuff like that. So one of my cats has a medical condition and I'm extra careful with her food and water etc. Her food bag wasaccidentally cut opened by a family member. I was crazy annoyed because I couldn't find a way to close it air tight. Her food gets weird if it's air tight so anyway I was angry and threw some tupperware and then cried.
Soo the question is am I becoming a person like those characters in movies that are psychotic and don't like anybody touching or moving their things and live far away from any human being? ( also I must mention that I was very hungry when all this happened) once I found a solution, surprisingly I was suddenly calm
