My brain works slower than it used to

I hate the way my brain works slower now.  It takes me longer to think of stuff now.  I put my foot in my mouth a lot more now.  I tend to so whatever comes to mind on accident.  I find myself apologizing more now.  I feel like a retard now.  I try to act normal but I know that I am not.  I just hope I am normal again.  I feel like i will have breathing and brain problems for now on.  I hate the way I can not do the things I used to.  For example, I am making a turkey cake for Thanksgiving and of course I can not do it myself.  I have to get my mother to help me ice the cake.  But I never could Ice a cake before.  I want to open a bakery one day but that probably won't happen because I suck at making cakes.  I know that I am being negative today I'm just tired of not being able to do the things I used to.  I'm fine with no contact sports and no amusement parks.  I never did those things before so its not a big deal.  I just hate not being able to go on long trips anymore with my family.  I really want to go to Washington D.C. this year for the snow.  But if the plate is in I can go. But I don't expect the plate to be put in for a while.  I not expecting anything anytime soon because I know it will be a while.  I know I should be used to being treated like a fragile flower because that  is how it was when I was in the hospital.  But it really sucks now that I am home.  When I was in the hospital I did not mind it.   I knew that how thy have to treat all their patients.  I just hate being treated like something that might break if everyone does not walk on eggshells.  I miss being an actual adult.  I having a job.  I miss going to school.  I fell as if I was kidnapped out of my life.
