I have pretty big hands too, here's a couple of comments:
- Yes, it's a bit of a handicap, but tbh after enough practice it goes into the background and more important things such as general talent, amount of practice etc. become much more determinant of your skill
- Even small-handed people have to get used to how their fingers interact with the strings. So, you might be over-attributing your struggle to the size of your hands
- Guitars come in different sizes. That is, especially the fretboard's width is dependent on the guitar model. You should look out for guitar that play to the size of your hands.
- There's a couple of upsides to having big hands. I for one have never had tendinitis in my hands due to guitar playing, and I always thought it's because relatively speaking I exert less force than the average guitar player
