As a balance to some of these sad posts can I tell you about my friend?
She suffered very severe pnd which was eventually diagnosed as bipolar. She was bed bound for months, unable to function.
Her recovery and, crucially, long term maintainence has been very multi layered. Therapy for several years ( group), strict adherence to her meds, plenty of sleep and a very high quality diet, works part time, yoga, gardening, dog, drinks in moderation only. She also refuses to do things she really doesn't want to do.
If that makes her sound selfish I will add that she has two happy and healthy adult DC, is a teacher, has a great marriage and cares for her very elderly mum.
She's the sanest, funniest and most grounded person I know. She only confided in me after being friends for some years. Her colleagues have no idea.
So yes, recovery and long term happiness is very possible but there no easy fix and you also do need to be someone who responds to the meds well.
Best wishes for your recovery.
