Lately I've had immense health anxiety after weed led me to probably my worst mental health ever. Someone at my job (a customer) died over the weekend and all day I've had intrusive thoughts like "youre next" and fear of dying in my sleep. I've had a few bad nights of sleep because of similar anxiety of racing thoughts about dying in my sleep. Any ideas on how to combat this? I just want a full night of sleep and to think I'm not going to die in my sleep. The stress is probably hurting me.
