I think we all get discouraged at times. Just leave it for awile and do something else you enjoy. I had the problem recently of feeling sorry for myself because I cannot afford fabric and such right now but, I discovered that I had a baby quilt to get don in one week and just said "Lord, show me what I have that I can use." He came up with enough pieces of this and that to make a nice quilt.
You will get a lot of encouragement here so use the board as often as you need to to talk to others.
