Navigating Life with 12+ Chronic Conditions

I’m 19 with 12+ chronic conditions. (Some medical some psychiatric). I’ve never met a single person with as many chronic illnesses. Nobody understands what it’s actually like. It’s so difficult navigating it all, taking all my meds, and seeing improvement with any bc there’s so much to deal with. How do u guys deal with the day to day life thing when there’s so you have to deal with and suffer through that nobody else seems to understand? All of my illnesses are invisible and everybody just assumes I’m a simple over dramatic teenage girl, despite rarely talking about any of my conditions. It’s just sooooo hard to manage, how do y’all do it? Do any of you have as many conditions as I have? I often don’t even know what’s causing what which makes treatment/improvement near impossible.
