A place of doom, an institution of desolation, a jail of misery - going to hospital

Please briefly elaborate on one of your extracurricular activities or work experiences. (150 word limit)
A place of doom, an institution of desolation, a jail of misery; these are some of the things that come to mind when people think about going to the hospital. However, I have found that I love volunteering at Memorial Hermann Hospital every Monday. There, I help with whichever department I am assigned to on that day. I can be putting filters into equipment boxes at Central Sterile, sterilizing beds at Post-Anesthesia Care Unit, or making packets at the Outpatient Lab. When I am not sent to a specific department, I discharge patients in a wheelchair whenever patients are ready to go home. My favorite thing about volunteering at the hospital is that I can help the nurses and patients in a small way while creating lasting friendships with the other volunteers. To me, returning to the hospital is not a chore but a joyous return to my second home.

Nice work!

I think that everything flows along smoothly, except the first sentence. I find this to be quite...strident? It seems a bit too harsh, the way you are exaggerating how much people tend to despise hospitals. Perhaps you could change that beginning to be more gentle. Make it fit in better with the tone of your last sentence (joyous, second home).

But other than that, I think you have done a great job with it.

Is there anything else in particular you wish for me/everyone else to look over?

Best of luck!
