Dreams.... To Follow or Give Up

Some times it seems that I'm being given signs to keep believing that one day I'll have my dream, and then there are days when I think it is useless and just to give up. How do you know when it is time to let it go?? Is it a feeling? Are there definite signs??? Do I keep pushing? I'm not sure any more. I'm 47 years old and I think it is time that I redefine what is important to me. I love animals but I know that my husband does not share my enthusiasm for them. I love writing, but in the last few months I've had signs that maybe it is not to be... I finished my book Scattered Thoughts and I really would like to publish it. Even if I self-published it would be a goal that I accomplished this year. However, I know there are some things that would hurt people if I published it, and that is not something I want to do. Even though there are no names, of people directly it would make hard feelings and there are already enough of those I feel like some times. I don't know how many times in the last few months that I've been told I need to let go of the anger, and the funny thing is I'm not angry. I've been told I'm bitter. I don't see it... I've been told I'm depressed.. maybe. I've lost a lot of good friends since I quit corporate America. I don't have any close friends and I was even told that was because I push people away. Maybe? So when do you know to call it quits? When do you decide it is time to let those things go, and just try to make it in the world? Maybe it is time to go some place new and start over? Maybe I am a bitter angry person and that is why I can't see the things I need to see. I guess I'm just questioning things. I'm having a hard time staying focused on the present, because the future is so unsure. I just don't know....
