First and foremost listen to your body/instinct/gut. Ppl change and so do we, you don't need to train the same way because your not the same person.....know what i mean. I would recomend either joining a different gym then your used to or join and go at a different time then ytou used to. Reason being your not influenced by familiar ppl when you used to work out and there will be no pressure to be the "god" you once where. Do what's right for you and yours and well grow up pride and ego never usually work against you as you age. Fuck everyone else and what they think!
