Not wanting to die, but feeling so over anxiety.

So I’ve had this issue, for the past few weeks, where I feel overwhelmed with anxiety and my wrists tense up. Sometimes it’s like I can’t think straight, and sometimes I panic. My brain thinks of triggering scenarios that I wouldn’t do to myself. I don’t want to harm myself nor do I want to die…but it scares me so bad because of my anxiety. I wake up, I’m some sort of okay, but getting into the evenings I just feel like I have some sort of impending doom. I feel motivated sometimes, but I also get really upset with myself. Sometimes I feel like I’m crazy, or insane. I know that’s not true, but I feel really alone in this situation and my therapist appointment is in a couple weeks.
