There is help here and that's so nice to know. I'll just say that if we are prone to depression or anxiety, etc. these issues are likely to return. We may get days, weeks, etc. of reprieve but whether they are organic or conditioned, we must remain vigilant.
Sometimes therapy is in order, or meds or our own ways we've discovered that help us cope. For me it is CBT, journaling, yoga, tai chi, meditation, reading, thinking, learning, even reading and posting here. Hope this helps some.
