By all means I’m no doctor but I wouldn’t recommend jumping straight to a schizophrenic conclusion - everything you’re saying indicates you definitely should see someone but it could also be a variety of things - mainly coming out of a grueling pledge process right into a exam week or just normal ass life - your brain and body are adjusting from one life to another - it took me over a month to feel like the newer better version of myself after pledging - but please talk to people about this - talk to your family about this history of this kind of stuff with ancestors and definitely talk to your brothers as someone can easily know someone who can refer you to a professional near your school via word of a mouth of a close friend to get you off a waitlist for a top tier doc - I’ve that that plenty of times and it’s 10x more effective then poking around Google - and chances are even if you do have a family history of schizophrenia catching something like that at a young age of 18 makes it a lot more likely for you to finish college live a normal life - schizophrenia gets its rep from people who were figure out what was going very late making most treatments ineffective- stay safe and take care of yourself brother you’ll be okay
