Panic Attacks. Should we take him to?

My boyfriend has had an episode of severe panic attack. The following  symptoms and things that have come up since the past 3 days: Sleeplessness,Intake of marijuana, sudden behaviour change, life history playing like a movie in head, turning violent at times, increased heartbeat, mistaking people for someone else, crying suddenly, feeling of guilt and asking for forgiveness. Unemployed since the last 2 years, under constant pressure to find a job, failed marriage 2 years back, has a history of sexual abuse and emotional abuse in childhood, seeks sexual pleasures out of committed relationship repeatedly, lies about trivial things, pretends to be someone he is not. Had a similar episode 5 years back. But nothing after that apart from occasional angry outbursts. What should be done at the earliest so that the problem does not escalate. What kind of mental health professional should we take him to?
