When I have hit a plateau I found that adding a good fat like almonds to my diet helped. For me it might be because I keep a very low fat diet.
When I feel low spending time with my dogs helps. I take them for a walk in the evening. We come back and sit on the lawn. I pet them and talk to them. Under the night sky the dogs listen and nuzzle closer. Somehow the problems disappear.
