Hi! I'm not sure how helpful this will be, but I'm 18 and just accepted Christ into my life last February when I was 17. I did go through a phase of struggling with faith; I'm not sure what your struggle is but mine was doubt. I didn't doubt in the existence of Jesus or Heaven or anything in the Bible, but I doubted myself, questioned if I had done enough. I kept wondering if I would be one of those people who get turned away as described in Matthew 7:21-23. On top of that, as someone who never had friends, I longed still very badly for good friends, which I believed to seem as though I was saying God wasn't enough.
What I learned through this is that the first steps into any journey are always the hardest. I think everyone on here can agree that a walk with God is not easy, so you can bet those first few steps are going to be like walking on little Lego bricks. That is when I held firmly to this verse, "Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance. Let perseverance finish its work in you so that you may be mature and complete, not lacking anything." (James 1:2-4)
I further learned that when we are still trying to get our bearings in this newfound faith, Satan strikes the hardest. I 100% understand feeling lonely or wanting a good friend group, I still haven't ever had anyone at my house or introduced someone to my parents. One of the first things God says about humans is that we shouldn't be alone, He suggests we need companions (Genesis 2:18, Ecclesiastes 4:9-12), but the search for that can be used by Satan. He'll make us turn to bad influences out of desperation or fear of being alone, he may turn us to doing rotten things for the acceptance of people who wouldn't actually care about us either way. So do be careful in the company you keep.
Overall, though, God always knows what He's doing and what is best for you. This phase is all about seeing if you'll give up or overcome in improvement, to prove your dedication and genuine thirst for the life. (Do you ever forget your point in the middle of explaining it because that's the wall I just hit🤦♀️🙄) You'll find a good community, just stay true to yourself, don't give up in faith, and shine for Jesus. I am positive that you'll attract the best people, the type to stay by your side in the long run.
Hopefully this made sense, I'm not good with words (plus it fell off at the end due to losing my point🙄🤦♀️)and sorry for leaving you a book to read haha! Good luck
