I need help please

Hey so, I am new and I found out in a counciling session that my anxiety and depression may be working to get to make me have gruesome thoughts,seeing things, and sometimes hearing things. Or I may have low key schizophrenia , I am scared because if it gets really bad I could go to the mental hospital. I can't tell my friends because if it gets out in the small town gossip I could be taken away as a threat. I am scared but at the same time I don't care. I also have suicidal thoughts. How should I react?
