I have been halucinating alot lately my family told me

Patient: I have been halucinating alot lately. my family told me that i have been saying things that are not normal and seeing things that were not normal. they said that i could not even recognize them when they asked me who they were. im really scared that i might be loosing it. my mom took me to see a doctor and he gave me this medicine:-Amitriptyline. so i did not take it because my mom said that one of the side effects of this medicine is that one might want to commit suicide. please help
