Does anyone else experience something like this?

At the beginning of a depressive episode you counteract the depression with an increase in activity in hopes to prevent a full blown depression?
In my case lately I've been more sexually active, hiking a bunch, buying more stuff than usual but it's not out of being impulsive it's simply to just not feel like a steamy pile of ****.
Or maybe I'm describing a mixed episode? I don't feel any bit manic (minimal agitation, sleeping is fine, no racing thoughts) and all my actions are purposeful.
