Hey there,
I am so sorry you are struggling. TIME is needed to be able to function. Be kind to yourself! After my first MVA (1st of 4 in 5 years, people just like to hit me I guess) I tried to go Christmas shopping, my daughter dropped me off, and I lasted 10 minutes. PCS patients are EXTREMELY sensitive to sounds, lights, noise, crowds, it waxes and wanes still for me 7 yrs. Later. You are not alone!!! Be kind to yourself, it will slowly show improvement. My Neuro Doc said diet and hydration, and SLEEP are EXTREMELY important. The brain you jumbled up he said is like tangled Christmas lights and the neurons and all the "wiring" need to put back together. You WILL get there, so hang tough!!!! ❤❤❤
