Sorry things are so rough for you right now

Is there any way your wife would consider coming to a therapy appointment with you? Maybe even just have a phone conversation with your therapist or meet with them alone while you watch your son? Maybe hearing it from an outsider and a professional would help her to understand what's really going on and that you're not just being lazy.

I know it's hard to feel like people don't think mental health is as important as physical health. Very frustrating when you're already not feeling your best...

Good luck
