do i tell them?

In need of advice, its a bit long so thanks in advance. I have a group of friends it was more like a mothers group, i wasnt in the best frame of mind back when we started the group(although they were never aware), i suffered depression and anxiety and was dealing with relationship issues and ended up moving interstate, Fast forward a year and a half and im in a much better place mentally and physically and moved back to the town i was at but i now feel alienated and have no friends, All the ladies from my mothers group are no longer interested in catching up with me and i feel they only talk to me because they feel obliged, but seem to make time for each other (we would meet once a week before i moved away). None of them are aware of what i was going through and im not sure if i should just move on without them or if i should come out and explain to them the person i was then isnt the person i am now
