I think I might be schizophrenic, but I'm afraid if I bring my concerns to a doctor, they'll tell me there's nothing wrong even if there is, because I already think I have it. What do I do?

Research the doctors in your local area & find one with a specific interest in schizophrenia. I have a chronic illness and the best think I ever did was find a doctor that deals specifically with my illness. Doctors that spend a lot of time dealing with a particular illness are better trained in doing so. Definitely the best thing I ever did was seek help from a general practice doctor that pretty much specializes in my condition. They seem it every day treat it every day and are a lot more caring and compassionate to people seeking help with their speciality.

I know you are afraid but if you are struggling the best you can do is ask for help. It is scary and some people suck, but you can take baby steps. Try to talk to a therapist and tell them what you are struggling with and they will probably recommend seeing a psychiatrist. Or maybe reach out to a psychiatrist to begin with. Remember that even if they are receptive to what you have to say, that doesn't make your struggles less valid, that means that you need help that only a person who is willing to understand will give. So even if they tell you there is 'nothing wrong' when you are experiencing whatever you are experiencing, you can go to someone else. Just please ask for help even if you are afraid, things will be much easier when you receive it. I wish you the best
