This is a difficult one for me, as I felt I had a calling but have now decided that it's not what I thought it was. I decided to give my life to God when I was about 13, then forgot about it. I went through a very rebellious phase later, got married at 21, and generally got on with life, but always felt there was something missing. Around the time of my marriage I started to take my faith seriously again, and at 26 started going to church and was confirmed. It became obvious to me that I needed to devote my life to ministry of some kind, just as I had promised so long ago, but I couldn't see how. At first I thought of training as a counsellor, but that didn't feel right. So I started to study theology whilst I worked things out. I becamse very interested in monasticism, and felt very drawn to that life, but as I am happily married that couldn't be it. I also realised I felt jealous of seeing women in clerical dress. Eventually I discussed thsi twith my priest and he saidthat he had thought I had a vocation to ordained ministry for some time. When a few others agreed, I decided to start the ball rolling for the selection process - and then found out dd1 was on the way. This came as a huge shock and I put everything on hold to concentrate on her. I came to realise that motherhood is a holy vocation in itself, and now believe that this is my first calling, because I woudl have been useless in any ministry had I not experienced parenthood for myself - I don't say this for everyone, but it is true for me.
We now have two dds aged 4 and 2 and ds on the way in the next week or two. For a while I still felt drawn to ordination and, partly as a way of meeting my need to minister, started a pram service in our village. I also write on spiritual parenting.
However, I've also changed my beliefs a lot. I've left the CofE because I am so disillusioned with it - I really am disgusted by the way it seems to actively go against Christ's vision of peace and justice. But I've also changed theologically - I no longer believe in the priesthood for a start, in the sense that I believe anyone can celebrate Holy Communion in their own homes, for example, or baptise their babies in the back garden. I also reject a good deal of the Nicene Creed, or at least coudln't say with any honesty that I really do believe in it. But I still feel called to something and have faith that one day it will be clear what that is - maybe it will be back as an Anglican, but my guess at the moment is that I will end up somewhere like the Unitarians.
I don't know if any of this answers your questions! If you feel drawn to ordination I woudl get some books on women priests to have a look at. Also, talk to as many people in ministry as you can. Look for opportunities where you can test your calling - I was recommended to try being a volunteer hospital chaplain or prison chaplain, but you might want to help at a Sunday club or summer festival like Greenbelt. There are two books to help you discern yoru calling - 'Live for a Change' is a general book and 'Called or Collared' looks at ordination and its alternatives. Both are by Francis Dewar.
HTH!!!!!!
