Feeling Alone and Discombobulated with an Allergic Reaction

anyone able to talk and just listen and empathize? I'm experiencing a random allergic reaction but have no idea where it's coming from and I feel like I'm not being taken seriously because I still can talk and breathe... the people who are supposed to be there for me, aren't or are overlooking it entirely. Ex) my mom: she had the audacity to write me a letter about my inability to keep a job while I'm having difficulty swallowing and am covered in hives and experiencing pain in my hands, feet, and knees. I feel so alone and discombobulated.
