Depression and anxiety through the roof

I got a letter in the mail from work on Friday just gone saying there have been serious allegations made against me and now I have to attend a meeting with my boss about it on Tuesday coming up.

I'm absolutely terrified right now. I feel like no matter what I would say, I'd only incriminate myself.

I can't believe this is happening to me.

I'm so anxious and depressed right now. I have no idea what to do and I have nobody to help me because I'm too embarrassed to tell anybody.

If I lose my job I lose everything I've worked so hard for and built up over the last 7 yrs.

I don't know what to do and I'm so lost. I wish I wasn't here anymore. Maybe that would be better for everybody.
