I have allergies that can swell up my throat, im out of work and wondered what to do if I ever run out of savings and cant buy Benadryl (diphenhydramine) or claritin?

Epinephrine rather. Such as eoipen is what you need in such case together with the antihistamine, appreciate that you aren't covered for now, you can still use free government clinics in your area, wish you all the best, goodluck.
