I feel for you. Guitar is hard. You don't say whether you're using an acoustic or electric but I'll assume acoustic because they're the most difficult to start on what with string tension and all. Maybe first thing is to get the guitar checked out and make sure the setup is good. The action could be too high which adds to your problems. If they think it can be lowered more then have them do that. That will improve the playability a lot.

Another option is to trade your current guitar in and get a smaller body guitar such as a baby Taylor. Frets will be closer together which will help.

Another quick fix is to capo the strings higher up the neck, say 2nd or 3rd fret. That will reduce the action and bring the frets closer together. In fact, try that first and see how things go before moving on to the other suggestions.

Good Luck.
