This same issue has lead to me seeing a therapist for the first time. Mine has led to me quitting a grand total of 5 jobs in the last 2 years. Anxiety builds up for one reason or another (I don't see my kids enough, a co-worker is difficult to deal with, co worker doesn't do their job and I have to pick up the slack... yadda yadda)

The most I can recommend is take it one step at a time. Tell yourself you're just going to get up and get dressed. Then when you're dressed, tell yourself you'll just drive to work. Once there, give yourself a moment (this is where I usually fail and end up bailing or calling in) then step out of your car and slowly walk to the door. Once you're past the door you don't have a choice and the issue of not going is no longer an issue. I always feel like such a child for thinking this, but I wish I just had someone to force me to go to work. I wouldn't have to make the decision myself and inevitably make the wrong one.

I hope it helps! I know the boat you're in all too well.
