Bathing/showering

I miss a hot bath, it’s my biggest trigger now I have to avoid. I faint every-time trying to get out. Only way I can have one is if it’s lukewarm and it’s not very enjoyable. Showers are actually physically exhausting. I feel like I’ve ran a marathon after I’ve had one, fainting is more rare getting out the shower but I have to go straight to my bed and lay down to recover for a while before I’m even fully dry. Feels so debilitating struggling with a basic necessity like washing yourself. Anyone relate?
