Dealing with Fatigue and Suicidal Thoughts

This week I have been dealing with so much fatigue. I feel like I need to sleep for a week at least. My pain levels have been relatively low for me, hovering around a 5. But the fatigue is almost unbearable. I'm at work and have pushed myself to be here every day. What really scared me was this morning while I was setting up my meds for the day I had the thought of wondering how much of certain ones would I need to take to not wake up. I've never been suicidal. And the idea that the exhaustion would trigger that thought process is scary. I don't really want to share this with my support people because they both deal with their own depression daily. I don't want to worry them. I really hope I can get some rest this weekend.
