I have experienced this from 3 separate jobs I’ve had but the difference is I can’t come up with a distinct reason why. I’m not harassed or degraded or mistreated. I’m well liked by all, accelerated through the ranks with ease and have received countless rave reviews from customers and clients. I’ve finally given up on maintaining employment and now am a stay at home mom. But this has left me feeling like a failure and insecure and lacking confidence. I can completely understand what you’re going through and I agree, it will likely not get better. I just wish that the reason I experienced these things was more obvious like in your case. It feels like I can’t find closure to that chapter of my life and can’t move on and completely heal from it.
