Do you ever have literal tears just sitting in your eyes because your mind and body are stricken with panic?

I was doing so well but I've been having a really bad flare up the last 2 weeks, having panic attacks almost daily.

I have a work meeting tomorrow with some very big people and I am frozen with fear. I just want to cry. They are really nice people too but I just can't help the way I'm feeling lately. I want to do well and succeed and impress them, but I'm so afraid of the panic taking away my ability to do so in the moment.

I'll get through it I know. My body feels weak. I'm dizzy. Just lying in bed trying to rest. I hate when your body just succumbs to the panic and anxiety and makes you weak and sick. I feel sick. I wish someone would just put me out of my misery because I'm so fucked tired. I'm so sick of this. Feeling incapable. Feelings sick. Feeling tired. Feeling worried constantly. The wheels of my mind constantly whirring. I'm so tired of being afraid.

Meditation doesn't seem to work for me. If I concentrated on my breath, it panics me. I try it anyway because I just want relief. They say it's like working out, you just have to keep at it to see results. I've been trying it for 10 years and it's still not doing anything for me. Well, sometimes it does, but it lasts about 5 seconds then I'm back to the whirring. It's exhausting.

I'm so frightened. Please god help me. 

P.S. I am on medication and seeing a wonderful therapist. It's just this work thing that is truly panicking me. And family shit. God just please give me some relief.
