Back to school 25yrs old??too old?


I went to college right after high school for dental assisting and finished I got married and got pregnant right after I graduated and I was so dumb and put my career in the back I never did anything with my certificate which I regret so much but oh well can't go back 😭 fast forward 5 yrs and I want to do something I can't work as a dental assistant cuz I don't even remember what I learned to be honest so anyways I want to go back to college but I'm so scared and I feel old already to go back plus my anxiety don't help any advice? Also I have my debt with Navient for my school loans of 5 yrs ago so idk if I could afford going back I don't think they would lend me money again and no rude comments please thanks
