If my parents belittle my mental illness and make me feel guilty for having it is that emotional abuse?

Yes, belittling your mental illness and making you feel guilty for it can be considered a form of emotional abuse. This behavior invalidates your experiences and struggles, which can exacerbate feelings of shame and isolation. Healthy relationships should involve support and understanding, not criticism or dismissal of your challenges. It's important to seek support from those who validate your feelings and experiences.
