I understand what you mean about using this as your only outlet. I feel that way most of the time. I don't know anyone, in person, who is going to through MS. And it's very hard for people to understand who aren't actually going through it, try as they might!
I wish someone had all the answers, I really do... "they" say they are getting closer to the answers!!! So I try to hang on to that.
But, it's okay to be down sometimes... Shoot I got down about things before my dx, so I'm still human... and so are you! WE ARE HERE FOR YOU anytime you want to vent! I have learned there are a lot of smart folks here at NT who know much more than me! Don't be afraid to depend on them!!!
You are in my thoughts and prayers,
~Friend
