Mid twenties is a long way from forever. My first divorce happened around my late twenties & I was devastated. When I finally got over the hurt, I started living my life the way I wanted. The first reaction is to find someone to fill that emptiness but it's probably not the best idea. Getting happy again about yourself should be priority one. I'm just now facing my second divorce. We have been together for 18 years and talk about being afraid I will end up alone! At 55, I don't have much left to offer but I know that I need to make the most of my life no matter what. So, I push through that painful period again and live for myself. Separation from a loved one is probably the deepest pain you will ever feel but your life will not end because you aren't with that person. Once you recognize that you haven't disintegrated you will be able to carry on a life that is actually pretty normal. As great as it is to share your life with someone, being on your own has some wonderful advantages that you should take advantage of.
Peace
