Can you call this guilt?

I feel bad about lying to her, she reminded me so much of my other friend. The one who originally helped me in the first place. She was so kind and had dark hair and a gentle smile. She had an even funnier laugh. This friend however seemed to have disappeared from my view. In doing such, she became out of reach from me. She when I heard her speak, this new woman who would become my friend, and she sounded so similar I became over joyed thinking that maybe I had found another person I can trust. So when she asked the question, 'have you any recent suicidal thoughts.' I panicked and ended up lying to her. 'No.' I told her. 'I dont.' I mean recently can be anywhere from a fee days to a fee weeks but when I actually thought about it. The very moment I was being very honest. I couldn't breath, my very own clothes were holding me hostage, so tight that it hurt. When I tried to breath it made me smile knowing that I was actually losing air. Would I have told her? Would I have told either of them? Have I ever really been honest about it, to anyone? I dont want my friends to have to worry, but would lying make it any better? Is this what people call guilt?
