Zane,

Sorry for your loss. Your dedication to your friend is admirable.

Yes,
Symptoms like you are experiencing are not uncommon. Your brain endured quite a load of stress while you cared for your friend. This stress, coupled with minor depression from the grieving process, creates a toxic effect on the brain. The cognitive deficits are a result of this overload.

I would suggest finding a neuro-psychiatrist for an evaluation. I would also get onto a high nutrition diet with supplements, especially those formulated for stress.

The PCS/Multiple Impact Syndrome brain is already in a state of compromise and this extra stress just pushes it past its ability to cope.

I experienced a similar situation back in 1982 after being ripped off for more than half a million dollars. My PCS/Multiple Impact Syndrome (13 concussions) combined with the stress to leave me like a zombie. I could not function. I have old photos that show me looking gaunt and pale. A ortho-molecular psychiatrist helped me recover in just eight weeks. He gave me B-12 shots and got me on a good diet with nutrition supplements.

btw, Our wonderful courts helped me eventually recover about $60,000. Never trust judges, attorneys, loan officers or real estate agents.

But I digress.

Seek out every opportunity to reduce stress in your life. I wish I could help you find a good physician. They are like hens teeth to find. Be persistent. Ask questions. Maybe a grief counselor could give you a referral to someone who can help.
