You are not alone and I think most who have this injury expeirence what you do. Before my injury I was very articulate and now I feel like someone has stolen half my vocabulary at least. In conversations I struggle to find the words and frequently mix them up. It does often get me funny looks but I soldier on. I to feel frustrated at the memory issues, mine are short term but trying to do a complicated tasks with many steps is frustratingly time consuming. While I am new here and my injury is recent, 5 weeks ago. Reading these posts is carthetic and reaffirming it is in my head but it is very real. Find a good doctor and if you need it lawyer.
