Quitting isn't an abyss. I can see that it would feel like one if you were truly bonded to the job like in a routine & getting paid for it. I remember years ago I was working at dead end job & I took a dare - a plunge into something else and was scared to death because i was leaving something that was at least secure. It all worked out in the end - was glad I took the plunge! Well, good luck to you!
