So, I literally posted something days ago, but Phil isn't letting it through, so...
Oh yikes...hopefully it was the sugar, but if it wasn't...I'll briefly explain Bipolar Disorder (mods let this through please)
Bipolar 1 is when you experience several days worth of hypomanic episodes and several days worth of depressive episodes, with a few normal days in between.
Bipolar 2 is when you experience less frequent hypomanic episodes and more depressive episodes with a few normal days in between.
Hypomanic symptoms can include disconnected and very fast (racing) thoughts, inappropriate elation or euphoria, inappropriate irritability, increased talking speed or volume, markedly increased energy, poor judgment, etc.
Depressive symptoms can include difficulty concentrating and making decisions, decreased energy, feelings of guilt, and worthlessness, insomnia or oversleeping, loss of interest or pleasure in hobbies and activities that were once enjoyed
I really hope that's not what it is. When my therapist was first trying to figure out if I had Cyclothymia (a more mild form of it) it was scary. And it will be scary when you don't realize exactly what it is and how to get help. But just have hope that things will get better.
