Struggling with Mental Health and Relationship Dynamics

the past few weeks it seems like whatever it is is kicking my butt I feel more mentally active than physically, and I can't seem to feel like doing anything other than sitting on the couch, mobile phone gaming and watching youtube, save for using the restroom and eating at times that arent as normal as they used to be. my bfs work schedule got jostled around and soon its supposed go back to normal but its hard to not feel stuck, worthless and drowning despite some things in my relationship getting better but not that they were bad to begin with hes super supportive and caring even if its hard to see or accept without it being "dramatic" I have no meds and my coping mechanism is slightly compromised due to the fact that even though I have permission I want to be able to sleep with my bf again before resuming friends with benefits (our relationship is complicated/non monogamous) sorry for the vent hope yall have a good day
