Does anyone feel like ending my your 2nd relationship after divorce is almost worse than your divorce?

Just curious on what you guys think I feel like an ultimate failure like I gave everything I had and maybe I could've given marriage, but I knew that my marriage wasn't going to resurface. Just feeling really lonely and down and kind of isolated. Don't want to talk to anybody about it. Don't want to date again . really haven't been this down and out and depressed and just super sad in a long time. yikes !
