Struggling with mental health stuff..

Backstory- Recently graduated with my Master's degree in Social Work. Already in a ton of debt from school and owning a home. Three kids, married, Demisexual, have a job, all that jazz.

Issues right now- Dental and medical stuff hit us pretty hard this last month. I am struggling to stay above it all and think that things are going to get better. The thoughts of worthlessness are coming up heavily right now and I am concerned for myself. Do I feel that I will end my life? No. I am more afraid that I will do something stupid and cause harm to my family financially. I am not going to physically harm anyone, but god damn if I can't just have something nice happen for a little bit of time before the shit hits again. Dunno where to go from here or what to do really, kind of shouting into the void.
