Agree. Under no circumstances should you do anything more in terms of contacting colleges.
You should, however, see the guidance counselor, if only to get some reassurance so that you can relax.
If anything further is to be done (not likely), it needs to be done by the guidance counselor. Why? Because the guidance counselor is viewed as being credible. The guidance counselor is the person of contact with colleges. The guidance counselor will be able to answer questions that might arise from colleges.
Relax. If you have applied to a range of colleges that you can afford and that interest you, you will go to college. There are still plenty of great colleges that are accepting applications (partial list here), if you feel you should submit some more apps. Like any other nervous student, you just have to wait now.
