Op, first, you should know that it's okay and if you sent it to the right address, it will get there. Sometimes transactions get stuck, and I've experienced situations with transactions stuck for 10-15 hours. My friend once had to wait for something like a week, even. In the end, it's just a matter of time. Now, can you show us the transaction? Is it still stuck? Also, do you remember the fee you paid? There was a spike in average fees recently, and it's often in moments like this that your transaction gets stuck because the fee is too low now. For instance, $3.55 is currently the average fee. You can also calculate the fee in another way, of course, but it's just a useful website for beginners, IMO. Chances are, you set the fee too low, and it's just best to wait it out until the fees get lower and it will get confirmed. But the question is, of course, how low you set it.
