Is life long medication the only solution

Daily sweat therapy hasn’t done anything for me for the past 4 months, diet changes, supplements, nothing has worked.

Claritin and zyrtec are the only things that have worked, but I stopped taking them because I don’t like the idea of having to take them forever. What if my tolerance builds up and they stop working, what if I suddenly can’t obtain them anymore and have to go the through the withdrawal symptoms. I’m only 17 and the idea of having some pills control whether I enjoy life or not for the rest of my lifespan is honestly depressing. Any advice
