I do have such a difficult time with the higher power. I feel like if I could overcome this, many things would be easier. I just don't think I can force it for myself. I admire those who have this, maybe it is just not my time right now.
For me, it does not seem like being positive and making peace are the same or even related. I do not feel like a negative person but am very much a realist. One of the things that cause the most disappointment, anger, depression, etc. are when our expectations are far from what actually happens. When I say "this is as good as it gets", that is likely very reality based, and doesn't mean I will quit trying.
Our economy is in bad shape, my health is in bad shape. When there are financial struggles or when I can not accomplish what I want to physically, the reality is that it will not likely get much better. There may be periods that are a little better than the moment, but I do not expect any long term period of stability of a better time. For me, that is acceptance yet is at times very saddening. I am getting older, I have a debilitating illness, I am on a small fixed income, I am getting older. Now what I do with that is a different story. There are times when my attitude dips, but I am pulling myself up much quicker these days. When those dips occur, I am sure that if I had faith in a higher power it would eliminate much of the negative thoughts and fears.
