I more than relate to that feeling of no one understanding, that isolation. I am surrounded by family that loves me...I should never feel alone or depressed but I always do. To be so alone in a crowd, the odd one out where no one understands why you feel the way you do, act the way you do or cant do what they take for granted.
You are not alone in those feelings, I and many others feel the same way and are there for you if you need it.
