The important thing with this is that staying holed up in your room, rummaging through the contents that you’d hoarded during your relationship will not solve anything.

What most people believe is that they cannot be truly happy if they’re not in a relationship. That isn’t true.
There are so many things that you could do which you wouldn’t have had the possibility to try if you were in a relationship.
You could even try out all the stuff that you loved and did before you were in a relationship but had to stop for the sake of spending this time with your partner.
