Hi Sotired,
Hope you are feeling a bit better now. It is tough when there are negative people close to you, it doesn't help with a disorder like this. I have had similar experiences with negative family members, it does make it difficult to focus on the positive. Do you have any friends or other family that are positive? Perhaps speak with them more but if not then there are heaps of people here to cheer you up when you've had 'one of those days'! Take Care, Jas.
