Am I alone ? Does anyone else feel this way sometimes

Somtimes I feel detached from my body and mind. It’s hard for me to concentrate. Reality doesn’t feel real right now and it’s scary. It makes me feel suicidal but I won’t act on it. All I can do is cry, I feel blessed that I have my sweet baby but then I feel sad for her because she has a mentally ill mom. I just don’t know what triggered me because i haven’t felt this way in a really long time. . . . Why am I the only one in my family that feel like this? No one else has experienced this.
