I feel like I lost the life I had after a brain injury
Why do you feel like you lost your life?
I feel like missing something that is not about physical abilities.
A brain injury is hard to recover from, if you are still having problems, you should seek help. The doctors might be able to fix and help you lead a more normal life.
I don't think it's primarily the brain injury itself, but how my family pressures me about different things.
I don't think that it is healthy to let the brain injury make you suffer, if it is continuing being a problem then I suggest you have your surgery as soon as possible as it may get worse over time.
