There was a possibility my bf cheated. He didn't and I completely trust him. However I still feel heartbroken and to top it off intensely guilty that I feel this way when he's innocent. What do I do I haven't felt this low in a very long time. I can't function,  in physical pain I'm zoning out completely crying a lot and just don't function as a person. It's like it really happened but it didn't. Help.
