I Got Stung By Wasp This Morning And I Am

I got stung by wasp this morning and I am allergic to them I can't afford a epi pen or go to the emergency room so I carry around benadryl and so I took a handful of it and I lay down for awhile and I woke and the swelling in my hand went down and my throat didn't feel swollen but since I've been up for a while I start feeling woozy again I feel dizzy and start sweating and my thoughts are not all collective so I just took some more benadryl is there anything else I should do or suggest besides going to hospital cuz I know all they'll do there is give me a benadryl drip cuz I've been stung before that's how I know about the benadryl oh and I ate some soda crackers for the nausea
