any medication that help with weightloss?

hi im F in highsch0ol junior year, im about 5'8-5'9 and i weigh around 190 to 205. i have tried working out consistently and lost around 10 pounds but gained it back almost immediately, ive tried eating healthy and diets that never worked, (TW: ED) ive tried starving and purging and abusing laxatives and such but nothing works, my mom mentioned that in highschool back in the 2000s she lost alot of weight with diet pills that are supposedly illegal now. I wanted to know if theres any affordable medication that could help me get to a healthy weight, preferably pills or such, i hate injections it makes me feel weird. if anyone knows any affordable meds please tell me! thank you!
