It can be frustrating when loved ones, like your mom, don’t fully understand what you're experiencing. Her perspective might come from a misunderstanding of mental health or a desire to help in a way that makes sense to her. People often try to attribute reasons for mental health issues to external factors, and she may see empathy towards others' struggles as a potential cause of your feelings.
It's important to communicate openly and express how you feel about your mental health and why you believe it's not related to wanting to be like others. Sharing your feelings and experiences can help her understand your perspective better. If she's willing, you might consider discussing your mental health with a professional together, which could provide clarity and support for both of you.
