I totally understand you!! Almost 2 years ago I left a job I was completely miserable in. It was like breaking up with an abusive boyfriend, after I was kinda traumatized for about 1 month, I kept telling myself I can make it I can do it..but I knew that I just couldn't bare it anymore. I toke a 3 week vacation to my mothers home town, out of the country.. No cell phone, emails computers or anything. Came back and applied for a different job. Now I still wish I was FIRE now, but at least I have a way better job than I had. Now I CAN make it, and I think that I should be FIRE in less than 5 years. Just keep going if you can, if not apply at other jobs, you might get lucky!!! I know that I did 😊
