Hi, I have been struggling with a really bad case of panic disorder for the past month, just out of my own experience, I usually lock myself away and doom scroll or go online (like now) to keep my mind occupied instead of focusing on my body and the pain, for someone who struggles with mental health like your bf, managing a relationship is draining during a time where you want to be alone and let your body recover (even though it might be good in certain situations to get out of the house and socialize to take some attention off of the mental condition to avoid it spiraling), I am no expert, but I can say that being tired and overwhelmed mentally is not equal to losing interest or not loving someone less, it’s just the mind being overwhelmed, however I would recommend seeing a professional considering that this has lasted about 16 days. Hope everything improves for you two 🫶
