Another option is to take lessons from someone who can lend you a guitar or help you buy something from a pawn shop that is not junk. Don't buy from a pawn shop without someone advising you, who knows guitars. There's a lot of unplayable junk out there that will just be a waste of good money. The bottom line is play, play, play. With all the advice on Youtube to get your going, there's no reason not to. You could also invest in some three chord song book once you get a guitar. Go for it.
Since you're a beginner, it is important that you play and write as much as possible. Building your skills is very important. It's very simple to get a guitar these days.
Check out Facebook Market Place. I just did a search and found an acoustic for $40. Go to pawn shops or second-hand stores, like Goodwill. Guitars will be relatively inexpensive there. It will also be helpful if you start hanging out with or networking with other musicians. One of them may have an 'extra' that you can borrow for a while.
There's also a guitar manufacturer in St. Mary's, just up route 255 from you in Weedville. It's Weinkauf Electric Guitars. This is a great place for you to visit. The reviews on Google show it's a small independent shop, owned by a guy who knows his stuff and prices things fairly. Shops like this are a valuable place for young musicians, especially because of the people who own/run the stores. They're almost always great mentors and open to helping you get your dreams moving forward.
If Weinkauf's is too far for you, look closer to home for any small music stores. There's also Guitar NIA in Clearfield with similar reviews. Again, look for a place close to you because nearly every town has a music store or someone giving lessons who will help you in your quest to get a guitar.
Your dedication will help you find a way to get the instrument you need/want. Don't allow something as simple as getting an instrument get in your way.
