My darling husband was alive, within weeks of both my children leaving, we were happy doing things together, just like when we first met. My kids were with partners, working so I felt good about it. It must be so much harder I would imagine when you are on your own, different altogether and lockdown has made it a 100 times worse. When things go back to the new normal, you will be able to join groups that interest you and expand your social circle. Life will definitely get better for you, just keep going for now,I know how lockdown affected me, on my own now, I would give anything to have the support of my husband and everything is topsy turvey but it is how it us and everything passes. ?
