I know EXACTLY what you are going through....my mom's depression was so awful at times, and her energy was zero too. Unfortunately, it seems like this a normal part of treatment. She was same situation...feeding tube, no swallowing at all, trach, etc...while visiting the oncologist, a nurse came in who specialized in wound care and the mental aspects of cancer. She recommended an antidepressant, and we just crushed it and put it in her tube. It helps, but takes at least a week of being on it to see any difference. Even then, the dosages may need to be adjusted, so do not get discouraged. But there is no reason they shouldn't prescribe something for your mom. I know how hard this is on you and your family...I was at the point I thought maybe I needed antidepressants, as well. I got through, somehow....I think mainly because of the support I get on this website, honestly. Don't ever feel like you can't vent here....we all understand, and are happy to listen. If you need to talk, feel free to email me or IM me.....good luck, and keep your chin up!! It gets better!
