Oh, momcat, you must have longer springs than we do. We have a few days here and there, it still freezes solid at night for at least another month or more, and frankly nothing is certain until May, really, and then suddenly summer is here and its 80 degrees! We had a heavy snow one year on May 9th, and I remember going out to shake the snow off the lilacs, which were heavy with buds.

Might you have some seasonal allergies that are affecting the depression in spring?
