Dear Amy,  

There are few details in your message, and to give concrete advice I would need more (age, studies, responsibilities, spiritual interests, etc...) to go on, so let me just say some very general things.  

Pray. Now that the thought has come into your mind, you have to take responsibility for it, to make sure it grows and bears fruit. Prayer is to spend time with God. Visit him in the Eucharist, go to Mass more often, speak to Mary and put your vocation in her hands. Don't ask so much for signs, as to get to know Christ so that he can transform you heart. 'Lord, help me love the things you love.' Thank him and spend time thanking him for all he has done for you.  

Then, start moving (supposing of course that you are old enough, and there are no signs that God is not calling you). You mention the archdiocese. That is one way, but if you are given brochures and information on all the communities in the archdiocese it may be confusing, because of the sheer amount of information on different communities.  

I find it much more helpful if you start off inquiring with groups you are already familiar with. You mention Mother Angelica. Without having to move to Alabama you can ask her convent for information, possibly visit them sometime. Then work from there. Sooner or later you are going to hear of or meet a group that for some strange reason you may not be able to explain completely, attracts you. Your heart pulls you back to them. Follow up on that one. 

Most helpfully of all, if you don't have a spiritual director you should look for one. A good spiritual director will know something about religious orders and will also get to know you well and have a good idea where God's grace is leading you.
