Lots of good ideas, yes seek counseling and a Dr. In my 51 yrs of teaching I have always had an outside diversion. For me it has been competitve archery, shooting, golfing, woodworking, metal fabrication and some I have probably forgotten. I would seek a respite from the constant barrage of dealing with students, parents, admin, co-workers home life. You need "Me Time" and make it fun. BTW all those outside activities were not at the same time. Good luck
