Hi there. I can relate. Not sure you remember my recovery story but it took me a long time to get back to work full time and continue with a fully funtioning brain. It's 14 months since chemo and 9 months since herceptin (mine was stopped early). I've only been at full time work since Easter.
I find now if I'm overstressed and overtired. ..well my memory just goes out the door. I can't recall details I normally can...names particularly. ..and I get teary. I have found that resting after work has been important. Taking time out during the day for a walk or something to just reduce stress.
I am on an antidepressant...have been for years. It doesn't cure it. But it can help clarify your thinking so you can do the things that assist in reducing stress. Without it I find my head is an endless record of worry and muddled thinking. The chemical imbalances of depression really mess with your head at times and make it so much harder.
I really want to study too, but I know currently I'm not in the right head space for it. Life remains too hectic and still full of worry (even if I pretend I'm not...it's really still there just lurking).
I hope the break from it helps and recovery will go on. You will get back to it, that I'm certain, but accepting you need to take some time out from it is great...when you get to that head space where you say " it's okay I'm doing this" I'm sure you feel better about it. Kath x
