I told my bf about my depression

My boyfriend knows a little bit about my anxiety, he's seen me have a panic attack before. Recently I've been really struggling with it, to the point where I've had suicidal thoughts. I told my boyfriend this morning because it was getting to be too much and I didn't trust myself. When I told him he basically didn't say anything. He gave me a kiss on the cheek but that's it. Then after just standing there for a few minutes he just walked out. I get that he could be a little shocked, but it's not the first time we've talked about things like this. More than anything it hurt me that I told him something so personal and serious and he just left without saying anything. Now I have a feeling he's not going to text or call me all day which makes me feel pretty crappy.
