Yes: You need to get help. See your general fp doctor and get started. Wanting to get better is great.

Good to Seek Help: It sounds like you are very concerned about your mood. It would be an excellent idea for you to seek out help, and it would be best to set up an appointment with a mental health professional with whom you could discuss your concerns.

DEPRESSION: Get an evaluation from a psychiatrist to help identify what depression/bipolar means to you and whatever else may be bothering you. Consider recommendations for medication if any are given. Get a referral for a reputable psychotherapist to speak with. Meds and therapy combined are most optimal; no just one or the other.
