Struggling with Emotional Regulation in a New Environment

hi guys! i've been struggling a lot lately with my emotional regulation. im currently visiting my partner (we're ldr) and he has cfs/mes (chronic fatigue syndrome) so he ends up sleeping more frequently for longer periods of time. usually im pretty good at dealing with that as we've been together for 2 years and known each other for 6, so we have a lot of experience with each other's conditions and symptoms. however lately i've been getting irrationally upset when he does sleep a lot, after 2-3 hours of being up without him. and because im in a new country and stuff, away from my usual hobbies and friends, it makes it even worse as usually i cope by being in the presence of other people or doing my other hobbies. i know my anger is really misplaced with that, and thankfully hes been extremely patient with me and my fear of abandonment that apparently extends to my partner sleeping a lot nowadays (like he's sleeping to avoid me, etc). however its been really hard w/o my therapist and my usual environment. plus the added autism diagnosis, the drastic change from the us to europe is insane and very upsetting. does anyone have any advice on how to do this? my emotional regulation and paranoia are getting to me a lot, so if anyone has any tips on how to deal with it better?? tysm 🖤
