I hope that if you're clinically depressed you've sought help/medication from a trusted clinician who'll maintain your confidentiality. I think we in the psych profession sometimes think that we shouldn't get sick like we often see in our clients.
I went through a depressive/PTSD period some years ago. It was difficult and scarey but it opened my eyes to many of the issues my clients face and has made me more compassionate.
I also am thinking, however, of changing fields just because I've been doing psych nursing for 18 years, have seen many extremes of behaviors (which all seem to be replaying over and over) and think I'm just ready to try something new. I get tired sometimes, too, of the depressed, whiny, borderline behaviors, and folks who only seem to know the "f" word.
There are many roads for us all to take, many ways to refresh ourselves, and many lovely and deserving people out there for us to assist through life's changes.
Best of luck
