Hey there... I know what you are going through and how you feel. I have PCS off and on for about 3 years and for the last 6 months its been constant. I know how you feel about no one understanding and people looking at you like nothing is wrong. Unfortunately, our issue is the brain and obviously no one can see or or feel the pain, unless they have or are going through concussions. I feel like my friends just dont understand whatsoever even when i try and explain its not a good deal and something I can just get over or put up with. Now i am just moving on trying to not let it bother me, its tough, but after awhile I feel better about it. if they are your true friends and family they will understand and be there through the end. If they arnt true to you and wont care to understand and just be there then they arnt good enough for you anyway. The less to worry, strss, and think about- the better...good luck and hope things get better, and they will!
