Shirley I'm so sorry you are going through this. You're right--- it's not fair!!!
Your'e also right-- that you can't give up-- your kids need and love you, and you yourself deserve inner peace and being able to take care of the needs that you have-- like dental work. Not familiar-- but there must be some kind of low-fee dental place? -- wish I knew more about that.
I can understand your being tired-- I feel for you. We're here to lean on anytime you want. Wish I could do more-- for what it's worth-- know that I'm here and listening. t/c
