It doesn't make the hard times any more easy to handle, it just makes your resolve to work out your problems that much stronger. God's eventual plan for your life may not include marriage. God may be calling you to remain single, so that your energies can be more fully channeled into service to Him. You may be called to the Ordained Ministry, or Religious life. No one can decide that for you, but through prayer and discernment you will learn to see that your specific gifts may be well suited for religious life.
Most young people consider religious life at some point if only for a moment.
If you would like more information you can contact the Vocations office in your diocese. They will be happy to assist you in your discernment process. Don't be afraid about making the 'wrong' choice. So long as your life honors God, He will be pleased with your effort. Many people change careers, or take years to decide upon what it is they really want to do or be in their lives.
