I would say, that the above post it a step in the right direction! Pray and think, pray and think! I'm actually listening to a set of CDs right now called The Art of Discernment by Fr John P Grigus, who is a conventual Franciscan, in Marytown, IL. He's a great speaker and was a friend's spiritual director. I've listened to the tapes before. It's just good to listen again. One of the things he says is that while listening to your heart is important, decisions have to be made with the head.
Finding a good spiritual director is incredibly difficult. There are those directors out there that will attempt to lead you down the path that THEY feel is the right one. . .instead of YOUR right vocation.
In the absence of a good spiritual director, or rather, until you find one, there are many good books out there that can assist with discernment. Christian Totality: Theology of the Consecrated Life by Basil Cole, OP and Paul Conner, OP is a great book, recommended to me by both PCPA communities in OH and AZ. It's good not only for those who are interested in religious life, but also the priesthood.
When God Asks for an Undivided Heart by Father Andrew Apostoli CFR is a good book for discerning any sort of religious life (meaning also the priesthood, which I'll just group together for this post).
Religious Vocation: An Unnecessary Mystery by Richard Butler, OP can also assist you in your discernment. His writing can sometimes be. . .abrupt. He doesn't have flowery words, he just straightshoots. And if I were to sum up what he's written, I'd have to say, he's trying to tell you not to make your discernment some search for a mystical experience, like hearing voices from the sky, etc. If you wait for some ecstatic encounter to fully KNOW vs. knowing as much as you can know, what your vocation is. . .you'll become a perpetual discerner, and you'll still be here years from know, intead of making a decision.
Oh yes! and another resource is a tape called Myth and Misconceptions Concerning Vocations by Fr Thomas Nelson O Praem. which is a great tape saying again, that about 1 in 3 are called, but so few actually answer the call to religious life. You can find many books at
IRL in their catalog section, under discernment. And they're all really reasonable.
Also on that site, you can find groups of communities of male and female religious. I'd suggest browsing through some of the communities. You'll see they are people, just like you, who accepted the challenge to live in community, offering all to our Lord, such a wonderful witness in today's secular, selfish society. See if, while browsing, any pique your curiosity.
In the end, ask yourself how much you're willing to give to our Lord. And when you offer this gift to our Lord, He'll bless you with guidance down the right path for you. . little nudges, if you will.
Oh and hey, if you DO wind up visiting communities, even doing an aspirancy (sort of a lengthy 'come and see') or even enter. . .and then leave, deciding it's not for you? There's no shame in that. And there's no obligation to stay during any of those steps. . .you would have such a long time before you had to make vows, to be obligated. Woohoo! With married life, you don't have the luxury of trying it out before commitment.

But if you visit and/or enter, but then leave. . .God works in all situations, and you never know why He's called you to that life, even if for a moment. . .it even could be that He wants to give you an appreciation of religious life, so that you can understand the decision of a future child.
And if you do discern that your vocation is to married life, recognize that it IS a vocation, so be sure to make it one! Meaning continue to place God at the center of your life. . .for no matter your state in life, your primary vocation is to holiness.
God bless you on your search!
