It's very easy to fall prey to self doubt; to worry whether the choices you've made, or the path you're following in life is the one the Lord would have you take.
But my friends, we are told to "do everything as unto the Lord", so as long as you are honouring Him with how you conduct your life, trust you're on the right path.
Don't over-think, or tread water because you're afraid you'll make the wrong decision. Put it before the Lord in prayer (even the smallest thing, cause He cares about them all) and then move forward. Embrace the life He has given you, with all the trials and all the joys - every piece has grown you to be the person you are today, and when you let Him shine through you, you can trust that you're on the very path He'd have you follow.
Remember, He will guide you always...He's incredibly faithful like that.
