Being single is not always the easiest thing. But being single can lead to a very fulfilling life. For example, when you're single, you can choose to travel randomly, you have the freedom of doing things, going places without the accountability to someone else. You can enjoy your hobbies, the things you love doing.
However, I do understand how it can get lonely sometimes. Trust me, I've been there. That's why being able to spend that time and figure out your relationship with God, your relationship with your family, and your relationship with yourself is important.
First, lets look at your relationship with God. This is the most important aspect of your life. Being able to put God first, and not put anything or anyone above Him. Yes, you may want a relationship, you may want to be married and have children, but never should you forget that God is number one. As soon as a relationship, or anything else for that matter takes the spot of always occupying your mind, of always being your focus, and first and last thing you do, you are putting that thing above God. Spend time with God. As you spend time with Him, you will be less focused on the little things. Like overthinking one text you sent, overthinking how you acted, fearful of what is going to happen. You have to be able to trust in God and have faith that anything that is going to happen is according to His will.
Second, your relationship with your family. The way you act with your mother or father is the way you will act with your husband and wife. How much you help out in the family is how you will feel in the future. The amount of respect you give is the respect you will give to your future spouse who you will be living with every day. Plus, once you're married you can't just leave or drive off. You need to be able to communicate. Learn to communicate to your parents, learn to have patience, respect, gentleness. Make efforts to have a relationship with your parents and siblings. It will help you in many ways in the long run and will also help in molding your character.
Thirdly, you need to know yourself. You need to be able to be thankful to God in all circumstances, radiate joy, know what you like, know your values, know what you need to be doing and how God wants you to help others. There are many ways God could be calling you. Start working with God on those ways. Ask God to reveal traits of character that need to be changed. Remember this is an important season that everyone will go through and that everyone has gone through. This period of singleness is very important for growth and healing. Therapy can also help to uncover wounds and manage them. Take advantage of the time you have to try out new things, to go travel new places, to get to know yourself, to get to know others, and most importantly, to get to know God.
