Rough night

So as some of you know today has been a particularly bad day for my health/heart anxiety and I really struggled to get through the day. Well I did and had a not bad evening but now that I'm laying in bed I'm having really bad anxiety and dealing with fears I thought I had conquered long ago.

Ever since I was diagnosed with sleep apnea I have been terrified of dying into sleep. I do use my cpap màchine pretty regularly but sometimes it's a struggle because the machine triggers some claustrophobic and choking sensations which in turn triggers my anxiety.

Wow I'm babbling long story short I'm freaking out right now thinking if I close my eyes I will never wake up due to a massive heart attack or brain aneurysm
