Hang in there. You went through a traumatic surgery so your body is in recovery mode and will be for a while. It sucks. After my TBI, I laid on my sofa for a year and did nothing but watch tv, try to sleep when I could, and try to eat when I felt like it. Then there were all the meds I had to get weaned off -- that was fun (sarcasm). So, I know how ****** you are feeling. When our physical body gets traumatized our mind has to recover from it too so it's super stressful. Rest. That's the best thing you can do for yourself. Cry, sleep, eat, breathe. Tomorrow is another day, as my friend Scarlett O'Hara quipped.
