I always feel as if my 'happiness' isn't necessarily 'real'...that it's somehow contrived or due to some chemical reaction in my brain.

Also, I think we Borderliners have a way of inevitably trying to sabatoge our own happiness because we can only validate ourselves via our negative feelings. It would make sense why I am more comfortable feeling negative than positive...
So yes, the guilt would be natural if I'm uncomfortable.

Try, try... to enjoy it and stay in the moment...as best you can. Much love.
