Anyone in my exact situation????

I can't function. I am unconsolable. I am constantly crying and screaming and so distraught. It has been 7 months since I found out the husband I loved more than anything has had multiple affairs throughout our 15 year marriage and I am still in complete shock. How did I miss it? I completely totally loved this man and the father of our two sons. Now, I can't do anything. I am so lost. Everyone I have talked to including my therapist say to focus on me and the boys. I can't. I can't stop thinking about him being out of my life. We planned our future together. How did he do this to us? I have never cheated. I thought I was a good wife and mother. Why didn't he cherish me? He wants me to stay in this house that we picked out together and decorated together and had lots of parties at and I can't seem to do it. Even for the boys...I can't do it. But then I think about myself somewhere else and I can't do that either. Please...is anyone else out there that is like me? I need help.
