It really depends. If those are your best memories, sure - that works and actually helps to even go back to things you enjoyed as a teen - this btw, has been as an positive example for people that struggle with depression.

But if those are destructive memories, that you want to return to and that are at the base of your misery, then no - that is absolutely worst thing to return to, as there is nothing you can change there and the things that are affecting you are coming from that already. So, pretty much this is the reason why it is important for kids to have stable normal life.
