Angry boyfriend,, Need help asap.?

My boyfriend has a lot of anxiety. He constantly worries about things and stresses over things. Not to mention he has a lot to stress out about, he got into a little trouble when he was younger and has a big court date coming up, he is scared that he may get jail time ( he wouldn't last in jail.. hes a pretty boy).. On top of that he works 40 plus hours a week as a tech support agent he deals with rude customers all day. He used to smoke weed for his anxiety and he (THOUGHT) it helped him out even though I was 100% sure it didn't ( i hated that he smoked). He recently was pulled over for a speeding ticket and had seeds in his floorboard.. the judge told him they would deffer his ticket if he could pass a drug test for the next four months so he hasn't smoked in almost a week. He was been stressing out so bad over the fact he cannot smoke, he even got frustrated when his seatbelt got caught behind his seat. He has recently been on edge. Every little thing I do seems to be a big deal. MY MAIN CONCERN: He has always been a little forceful when he gets upset like he would grab my face or hold on my arms firmly, but this week it has gotten worse.. The day before yesterday he laid on top of me so i couldn't move and held my face down really hard screaming at me to look at him when I talk to him (we were fighting ovbiously). He would squeeze my arms as hard as he could or pick me up and chunk me onto the bed. Last night he yelled in my face as he pushed his head really hard onto my head and also sat on top of me and held me down by my arms and face, I had a panic attack and he yelled at me telling me i was faking, I was hyperventilation and my mouth was so dry I couldn't swallow or catch a breath and he was yelling in my face to speak. I am really scared that this may escalate, I don't want to be in an abusive relationship.. I told him he needs to get help or I am leaving, He is incredibly sorry and has been crying non stop since last night.. he looks at me like he is so ashamed, I asked him to talk to his dad or a friend and he said he is scared that they are going to get mad at him for what he has done.. (he deff wasn't raised to treat women like that).. I don't understand where this is all even coming from, he has never done this before, I have never even seen him this angry before out of the years we have been together. He is honestly the sweetest person out there but then sometimes he turns into this and I swear for that moment the devil is in the room. I need some advise, where can I get him help that will actually help him work on his anger.. I dont need any (just leave him, your stupid for staying advise).. If he does not change I will for sure be leaving, I sure as hell am not going to be the victim here I've dealt with this **** in a previous relationship and I refuse to do it again..
