yea i kind of just switched to a one handed back hand 2 months ago
So it's safe to say that your one-hander is a work in progress, right? When I rebuilt my strokes several years ago - including a sound one-hander - it took a lot of months of deliberate work to reinforce the different footwork and timing that makes that stroke work. If you're not executing that stroke unconsciously yet, keep at it. It does take a while to learn the proper setup and stroke tempo to reach a contact point that's further ahead of us than a two-hander with a similar ball. Everything has to get going earlier.
If your wrist is hurting, it's probably trying to do some unnecessary work. Maybe your forward stroke isn't initiating early enough, maybe you're not swinging to a contact point that's out ahead of you far enough, maybe you're trying to use your wrist to help with generating topspin. Hard to say. If you were slugging with a strong hitter, the ball may easily have been getting "in" on you too much. Late contact with a one-hander can be rough on the wrist for sure. Be aware - the proper contact point on that wing should feel like it's further out ahead of your than with your forehand.
I'm now 51 and although I've tried several "middle-weight" racquets here and there, my backhand definitely suffers if I don't have enough heft and stability in my racquet to command the ball. In case you need a little extra stability in your own rig, it's simple enough to add only perhaps a few grams total to the hoop with lead tape, etc. It's also easy enough to just peel it off if it make your racquet feel worse.
Now that I've been teaching and coaching for several years, I'm a believer in players' aptitudes. Many can do fine learning a two-hander, but a few have a much stronger natural inclination to hit a one-handed backhand. It sounds like you're in this bunch.
Full disclosure - I also hit a two-hander when I need it. When I need to handle a deep drive off a short hop or fight off a strong serve with a somewhat aggressive backhand return, the two-hander bails me out there. But the one-hander is absolutely the better style when I can execute it. Hang in there and enjoy the journey.
