Just ended a 9 year relationship and feeling hopeless that I’ll ever find love again.

I’ll be 27 in 3 months and I realize this may be irrational, but I feel too old and “behind” after ending a 9 year relationship. We were engaged, but weren’t right for each other towards the end. It was a pretty mutual decision and I think I knew for awhile that we weren’t right. But, I was afraid of being alone for so long. I guess I’m just looking for advice on how to move forward. We were together since high school and the thought of dating is terrifying.
