Please do make an appointment to see a professional.

I only took online tests after diagnosis and I took a lot of tests. All positive but for many disorders I don't really have.

You should start a mood chart before your appointment. This will help you and your doctor determine how frequent and how intense your mood swings are. Also will help identify if you have any triggers.
