It’s been 9 months since I left my marriage and I’m feeling lost more than ever

Feel free to check my previous post for more context but I was engaged/married and I 27F left my partner 30M and moved out of the city in February. The relationship wasn’t going well for so many many reasons and I decided the best way was probably for me to move out and move to a different city. Well, I did that and it’s been HARRRD. The loneliness is intense and I just feel so so lost and afraid that I won’t find anyone, I feel like most men aren’t the greatest so even if I left I most likely won’t meet a great guy. So why not just stay and at least I’ll be married. I’m thinking of moving back with my parents so I won’t be as lonely and start my life over again. Has anyone left a long term relationship and found happiness?
