I hate being stomach sick and having allergies

I cant breath when im dry heaving from my mouth and my nose just doesnt work

can I die? please?

most people dont get triggered from being nauseous but when you try to kill yourself via pills at 14,legally die and come back and vomit up foam for 3 days and clear for 2 then well certain things can become so fucking triggering

I dont know whats wrong and im miserable about it because I hate being stomach sick
