I think it is often hard for a family to face the issues within it. I have an aunt with alzheimers, and even when she was calling my mom 10 or more times per day and having the same conversation, my mom was unwilling to see the issue.
My nephew is bi-polar, and the same thing. His mom understands and is hugely supportive, but his dad won’t admit there is a problem.
Psychiatrists don’t just randomly diagnose people with this disease. In order to get the diagnosis, there must be something he/she saw. Do you think the meds are helping? If so, you owe it to yourself to continue with them, no matter who else believes you have the disease. If you don’t think the meds are helping, talk to your psychiatrist and see if the meds can be fine-tuned or changed. What matters most is what you believe, and getting yourself the help you need.
probably because either (a) they are in complete denial or (b) they think that anybody, especially young people, with a mental health issue is ‘faking’ for attention.
