hi
the best thing for you to do is write down your symptoms, concerns, and take it in to a doctor so you can have a profesional opinion/diagnosis


this sounds like social phobia/anxiety to me

bipoar is a "Mood Disorder"
you cycle from highs to lows, often extreme episodes

some people can manage with therapy and not meds, some people need the support the meds can offer
but thats what they are, Support, not cures

btw you can have both GAD and Bipolar, although from what you write it sounds more like social anxiety
