I learned long ago that spontaneous conversation and comments tend to be superficial. Rather than feel a need to always have something to say, I slow down my thinking and focus on having something of substance to say.

It sounds like you may be suffering from depression. You should inquire about help with that. It is common with PCS. The symptoms can overlap greatly. Depression can cause memory issues and many of the symptoms you are experiencing.

When I am in a group, I rehearse what I am going to add to the conversation in my head. That way, when I speak, it makes more sense.

If your time with friends is with multiple people talking in a conversation, that takes a lot of brain power and focus to follow. Use this time to learn to listen. Women like it when a man has learned how to truly listen.

It sounds like you are putting too much importance on these social settings. If struggling with these conversations is so depressing for you, you really need to seek some help.

Regarding headaches. I have had headaches that were chronic for 6 to even 9 months after an impact. It just takes time. Sometimes, I would have what I called mud headaches. My head would feel like it was packed with mud with a dull pressure discomfort and slowed thinking. It took a long time for these to stop reoccurring. One might last all day.

I've learned that some of these headaches were related to my quality of sleep.

I hope the neuro can convince you to take it slow and give yourself a break. You are just too critical or obsessed about every little thing. Let go. Learn to relax and things will improve.

My best to you.
