Hi Nikki, welcome to the forums! So young and so much to deal with. Well, you're among friends now, and a lot of us can relate to what you're feeling. And as MJ so beautifully put it, you are not worthless, you have an illness that makes you feel this way. And it can be put under control. But it takes a lot of hard work and effort.
I hope you'll come here a lot and let us get to know you. I'm really glad you found us!
Hugs,
Greg
