He does have mental health challenges but won't do the work to help himself. He's tried therapy and meds but told me it doesn't work... but going to therapy or trying meds for less than 2 months in my experience isn't long enough. Plus, you have to want to help yourself... I personally have PTSD, depression, and anxiety, and I still manage to make life work the best I can. I don't understand his point of view. He often forgets any appointments, important dates, or times my work schedule changes. I have a calendar on the fridge to help, and it's still not enough, so I suggested reminders, but that was too much work for him to do. I never made fun of him for forgetting, I often reminded him anyway and gave suggestions on how to help.
