HELP, please. I don't know what to do.?

My boyfriend and I have been dating for almost a year now, and we have a wonderful & beautiful relationship. We both love each other very much, and want to make things work, but we hit a snag in our relationship about two weeks back, and have not been able to get over it. We have agreed to try and work things out, we love each other very much, but what is getting in the way is the severe anxiety that he is experiencing from the relationship. He is very honest with me, I know that I can trust him wholeheartedly, and he has been in an extreme state of anxiety that is only getting worse. We have talked about developing a plan to help him ease his anxiety.. and he has mentioned that he has tried come up with everything to try to ease it with no avail. In previous situations, the only way that the anxiety was remedied was by a drastic change.. such as a break up. We both do not want it to come to that, but if his anxiety isn't remedied soon, I don't know how much more he can take. I love him, and refuse to give up without a fight, and he is fighting as well. I know we can get over this, but I need help formulating a plan with some immediate results, as to the anxiety. It needs to be a plan that we can see and follow, not just a "take it a day at a time" kind of plan. If we can get over his anxiety (quickly, cos it is starting to effect him negatively), we can work on bettering things between us. We understand that process itself, will take a while, but we need an immediate solution to his anxiety. We have mentioned therapy for his anxiety, and we plan on pursuing that option, but again, that is a process that will take time, and we at least need a temporary and quick remedy that will help him ease his anxiety so that we can work on our relationship. Our relationship is far too amazing to let go of without a fight. Please, if you have any kid of suggestions on an action plan.. or any suggestions at all.. please help. Thank you so much.
