I think my boyfriend is bipolar because of how his mood goes from being super happy, to aggressive and blaming everything on me, then depressed about the terrible things he's said to me, how he's not good enough, how everything bad happens to him and believes life is nothing but torture and believes he should kill himself, then he becomes suddenly really happy again. Its been going on for about 2 or 3 years and I've once suggested he should go see the counselor, but he's very private and doesn't believe anyone could help him.
