Actually I can't really relate to what you're saying. I've been married almost 30 years and have two grown children. I love being a wife and a mother, BUT that doesn't mean it's meant for everyone.
God has given you unique gifts and talents, and since you're single, you can devote your time to them.
What I suggest you do, is to pray and fast. Seek out His will for your life and ask Him to show you where He'd like you to be, and how He'd like to use you for His glory.
Many blessings to you,
