"This month it seems like things in myself are more light, as if the usual obstacles have lost some of their gravity, or that my strenghth to counter it has grown."

Just wanted to add a quick data point that this matches my experience as well. Could just be that spring is here in earnest, of course, but still. After a bit of a dreary period I'm feeling "lighter in myself", like you said, and also more...peaceful is probably the best word, and at a sort of acceptance of the things I'm unhappy about but know will take time to change.
