Feel so lost

I feel so lost anymore. I have lost so much of myself over the years and despite trying to be positive about things. I find it more and more difficult as the days pass. I don't feel that most people can relate to what my heart says and therefore feel unloved by many. I had a big time reality check in church and it gave me a huge clarity with a heavy heart. I feel useless and unwanted in my life and in my family and not sure where to go. For the first time in quite some time suicide has crossed my mind.
