Should I be seeing a medical professional?

For context, multiple people in my family seem to think that there’s something wrong with me. Their primary reasons deal with my allegedly persecutory thoughts and skepticism in reality. I find myself moving closer and closer towards the idea that I’m the only “real” human while all other people were created by a God or otherworldly beings. Even now, posting this feels like I’m feeding into what they want of me. They’re trying to make me doubt myself because they know that I’ve discovered them. I think there’s a good chance of me being part of an inhumane experiment designed to test the psychological limits of humanity. It’s as if everyone around me was made to anger and sadden me for this purpose. They know what they’re doing. They were made for this; to test my limitations. I can’t maintain any type of relationship with people due to this. *Everything* upsetting feels purposeful. Additionally, I’m highly competitive in a way where I must be “winning”. It doesn’t matter if I’m truly “winning”, it only matters that the person thinks I am because their reasoning for telling me their troubles is an attempt to “brag” or demean mine. If someone is sick, I need to be sicker. If someone is hungry, I need to be hungrier. If someone likes something, I need to like it more. It goes on, but I think my point has been made. There’s other things I’d like to say here but I don’t want this post getting removed. They’re related to violence. Anyway, what do you guys think? Is there any reason to be truly concerned?
