I too am a HS teacher. I had to go on disability last year. It does suck. Hard to go back but we decided if I went back at a normal break in the year (after a vacation or start of a year) it would be easier. Although it's stressful teaching I'm taking 1 class and 1 moment at a time sometimes and it's working. I have great professional support but don't have friend support and it it hard. Not officially diagnosed because I deny my mania and insist it's just me being my energetic full of life self. The past 2 years I've tried many meds and I don't like any of them. Haven't felt heard though or understood so I am going to a new person, colleague of my awesome therapist so I guess I have to trust. Scared of medication that will make me gain weight (happened 1x already) and that caused depression.
Hang in there. I am here too.
