Hi, Willow.
You'll probably think that you and I have nothing in common - I'm Type 2, only recently diagnosed, and I'm an ancient and decrepit 63-year-old grandma - but your very moving post made me want to give you a big, big hug and tell you that you DO have what it takes to win, despite this horrible, unfair disease, which you don't deserve, and which has blighted your life for so many years.
The reason I say you have what it takes is because you have found this forum, and have the ****s to post a thread and say how you really feel. That makes you A Winner, right there.
I have a very dear friend who's a recovering alcoholic. He's been off the booze for 20+ years, but he's still very active in Alcoholics Anonymous. He explains this by saying: "The only way I can keep it (his sobriety) is by giving it away", which is why he actively supports other new members on a daily basis.
From what I understand of T1, it would seem that you've acquired a phenomenal amount of wisdom in the 12 years you've suffered from it, and maybe that's one way you could keep your motivation - by giving that wisdom away to others who are in dire need of it.
I'm going to follow your progress through the forums with interest, sweetheart. Sending you big warm hugs! xxx
