I can relate to feeling optimistic and then having a crash. Depression isn't a steady state. There are many ups and downs and it's the downs that can get us into 'trouble'. Most definitely make the call!! There are therapist that work on New Years Eve and New Years Day. It's a busy time of year in that profession around the holidays. If you get a therapists message machine tell them you are looking for treatment for depression. Also a therapist/psychologist can't prescribe meds so call your primary care doctor or a psychiatrist as well. I know how hard it is being a mom and having the need to be/feel strong. It's your turn to take care of yourself.
