disheartened

Today I am feeling very disheartened and I really hate feeling like this because I have a little miracle growing inside of me. But sometimes no matter how happy you are someone can still manage to bring you down.
I love my church and my church family but recently I've been made to feel unimportant and that the work that I do is taken for granted and unappreciated.
I am a person of very little words and very rarely speak out, my confidence isn't great when it comes to talking. But a few weeks ago I stood up for what I believed to be right and it caused a week of upset and grief, the things I said were taken the wrong way and whenever I tried to explain myself it was blown out of proportion and made things worse, In the end I apologised knowing that I was backing down on what I thought to be right because I knew that person was much stronger than me and had more of an influence over the church and the corps officer. It didn't matter how I felt and my feelings weren't really taken into consideration. It made me feel insinificant and I felt that from now on I should stay silent.
A big aspect of the corps that I love is the worship group, it always seemed to boost my faith and helped me to feel closer to God but recently I've felt that it has lost something, so I deceided to do something about it and try to get everyone together to talk about things, but that didn't work, although people were interested to start with they all started cancelling at the last minute, another sign that I shouldn't speak out.
I was told once that I had the gift of disernment - The gift of discernment is the special ability that God gives to certain members of the body of Christ to distinguish between truth and error, and to know with assurance whether certain behavior purported to be of God is in reality divine, human, or satanic. I use to experience a strange feeling when we had all the upset in our corps a few years ago, my heart would beat fast, I would feel breathless and dizzy... I'm am not saying that I am experiencing the same feelings now but I do feel that something isn't quite right in our church at the moment, maybe the devil is trying to get back in but at the moment I don't feel like I can say anything as I don't feel like I have the support or even the love of certain people. Over the last year we have taken on leadership teams so that everyone feels that they have a say in how the church is run... I'm not sure this is true, if so why do I feel so insignificant and disheartened at the moment.
