Sorry your feeling so low...

Bipolar typical doesnt change within minutes, but anything is possible. I do hope your able to get some help despite your parents being unwilling to help you.

Until you can get professional health .. Learn some coping skills to help you navigate the ups and downs ... Meditation, Mindfulness, health diet, Cardio or any intense exercise will help you burn off excess energy, Yoga . Good sleep hygiene.

Dont be worried if your Pdoc doesnt label you as Bipolar right off.. The main thing is to treat the symptoms . You dont want a Bipolar "label" unless it is necessary.

Take care
