First off, don’t think it’s because there is something wrong with you. You aren’t married for the same reason millions of others aren’t: this world has human relationships so messed that few begin, and even fewer are actually healthy, happy bonds. I have one foot in the secular world, in my job, and the other in the Catholic crowd, and I see it on both sides. It’s not you; it’s the world. And it’s not just Catholics who are lonely and depressed; people enter really dysfunctional relationships out of desperation
Second, sit and really think about the purpose of life. We can know theologically that we are here to work out our salvation, and that we’re made to be happy with God, yada, yada. But these words lose their impact when a person feels alone in life and sad. When you feel that depression coming on, bring your thoughts back to the thought that you are intended to find happiness in God, even if that thought is not as appealing as wanting someone to be with right now.
You might get married, you might not. But ultimately, you will be okay either way. And it’s out of your hands; there is really nothing you can do. And there is a relief in really letting it settle in that you cannot control the situation. You have to choose to focus on positive thoughts: you have a world of possibilities open in front of you. You don’t know what God has in store for you. And for sure, your life is not always going to be the way it is right now.
Lastly, do you get out much? Do you have things other than work going on? if not, go do something. Sitting at home alone will only tempt you to dwell on depressive thoughts.
I saw this clip on Dustin Hoffman a while back, and it made me think of all the beautiful women who are in your same position. It reinforces my first point: there is nothing wrong with you!:
