Trigger warning: suicidal ideation

Yesterday, I found out I fucked up our rent check for the second time in 6 months and it bounced. One more check bounce and my husband and I are out of a place to live. He was, understandably, upset when he found out and let me know that we may lose our rental because of this (he was very calm and truly not trying to upset me). I LOST it. This is just one more stressor in a long line of stressor recently and it caused me to spiral to the point of true suicidal ideation. I told my husband I was done. Had my husband not been here, I likely would have followed through, but he stopped me.

I'm less suicidal today but the anxiety is eating me alive and is making me feel more suicidal than I would if I didn't have this anxiety. I've been unable to eat, shaky, very nauseous, and obviously out of my mind with anxiety. I've tried yoga and meditation, will likely try to use some cannabis before too long, but I was curious if anyone here has any advice to bring my level of anxiety back to a manageable level. I'm also feeling extreme guilt over the episode and obviously over screwing up again. I feel like I'm going insane and don't know how to stop it without ending my life. If anyone can help, PLEASE. I need your help.
