Hurting again just venting?

im 13 and i have mild scoliosis i used to have moderate and i went to a chiropractor and im going through puberty and im starting to curve again and i don't like complain when others have it worse then i so i come on here so i don't rip my hair out with the stress and terrified of it hurting again im so scared every time i write about this on here i almost cry i think it's selfish to complain when others have it worse then me it hurts like it did the first time around more of a pain/ annoyance and i can get by but i want to cry every time i think about the future because before it was getting worse so im spilling my true feelings. i cant complain because ill become guilty and if i don't ill explode from the stress is there anyone who feels the same way? is there anything i can do besides guilt or stress plz help D:
