how do i cope with and accept my dx?

hello, i (19M) was just diagnosed with fibromyalgia. honestly, i’m a fucking idiot that didn’t see it coming. my mom has fibromyalgia and my symptoms got significantly worse after i had covid-19 in 2020/2021 (either end of 2020 or start of 2021). i also have BPD, autism and ADHD. the comorbidities are comorbiditing i guess?

anyway. i left my doctor’s appointment last week and i completely broke down. i’ve watched my mother deteriorate the last few years and i’m scared that’ll be me in the future. i’m in so much pain all the time. it feels good to be taken seriously after being told i’m overreacting for years. but fucking hell, i had no idea that getting diagnosed would hurt as much as it did.

my mom is quite dismissive of my diagnosis, during these last few years she has been assuming i’m making it up and that i’m just lazy, and even now when i’m diagnosed she’s not really very supportive.

how do i cope? what helps you guys? and how do i accept the diagnosis. i’m really praying to god it’s something else. i want it to be curable. but it’s not and i need to accept that.

thank you.
