Pushing myself too hard?

I am trying. I am trying so hard to be better again. I might be trying too hard.

I am walking into work almost 2 hours early today because I couldn't sleep. The nightmares are back. I couldn't go back to sleep. Every time I woke up from one, I put on one of my Calm app Sleep Stories and it would put me back to sleep, and insert me into danger. I just couldn't risk that again.

I am working 9-12 hour days. It's stressful, even though I love my job. I am also starting classes soon. Decided to try and get a Master's in Social Work so I can be better equip to help others out there like me... I just wonder if it's too much too soon.

I am sitting here, at my desk, with an anxiety level at about a 7, verge or tears, because I just don't know how well I can deal with the day today...

But, I don't want to disappoint people by not trying.
