I also feel alone , alienated from the practices of my social group and no one to talk to. It is sooo painful . My situation is like yours. While your friends are getting married and having children , my peer group is totally enjoying having the kids out of the house and most have reignited their love due to the lack of distractions . They travel and have big houses. But not me . My husband divorced me. So just as you feel you are missing what your peers are enjoying , i feel the same way . It's so demoralizing and destructive to self esteem
