I know how you feel and you're not alone, although somedays it sure feels like it. Thats why I like coming to this site, because there are people just like us who just want someone to talk to. Someone who understands and doesn't judge. Someone who "feels our pain" and knows we are not making it up. Some days I just feel like giving up and then I look at my 3 beautiful children and know that I can't. So cheer up a little, there are a lot of us out there and we can help you on the "bad" days. Whenever you need a friend you know where to come.
Good luck and God bless
