Miss my old job ?

I left my old job last august but I really miss it so much. Now I’ve left there is definitely no way I can go back but I can’t stop wishing that I hadn’t left in the first place. The culture in the old workplace was so bad, an alcoholic culture, bullying and many people left. My good colleagues left but then management got cleared out. The reasons I left were because I felt badly bullied and wanted a fresh start. I got offered many jobs and took on what I considered at the time the best offer. But dam I miss my old job. I know I can’t go back because I saw the alcoholic bullying version of the job and that was hell. But now I wish I’d just stayed put. I can5 get it out of my head and it’s torturing me. Has anyone else experienced this.
