Could I ever do anything right?

Ahhhh, where to start? So many thoughts rushing thru my head right now. As I sit here in Starbucks drinking a green tea frapuccino trying to get my thoughts lined up. It is so frustrating to see and feel that anything I do in regards to my responsibilities as a family man, I do wrong. In rehabilitation I do everything right and I put all my effort in doing it right and successfully. What I'm I missing when doing regular life things? I know that is not emotional. What could it be that I'm missing? I have a supportive and loving wife. I have a great support network. But it seems that I keep making the same mistakes that end up in things being messed up. Could it be attention issues? I don't know.
The path to recover from a brain injury is tough. To many things to figure out. To many things that will never be the same. Plus, I know I will never be the same.
Yes, I'm having a sad moment. Not depressed. Just sad. I understand that everybody gets sad and everybody have issues. But it seems that what I used to do naturally I now have to put extra effort to accomplish it. Could it be the impulsivity? I don't know. As I keep messing things up, it takes a toll on my family life. Even though I have an angel as a wife, yes, Roxana is an angel, and I know she tries her hardest to understand sometimes I know she gets frustrated and upset. It's hard for her to see that I'm a changed man after the injury. I do recognize is as hard for her as it is for me, and at times it might be even harder for her.
I just received a very supportive email from a very good friend as I was writing this. That email filled me with joy as it brought a smile to my face. Thank you Mercy.
I understand the emotional stages of healing. This might be part of them.
