I'm 35 too and I just completed an Lpn program, it's very intense but u can do it. So what if the 19 yr old students don't seem to be stressing most of them don't have as many responsibilities so its not as stressful for them but it's only the second month trust me if u stick around long enough you will see the stress. It's not going to be easy if it was everyone would be doing it. Hang in there and relax.
