The King James Version word for, "patience," is, "longsuffering." It's a more apt description of the process.
Because we see people that we admire enduring difficult things with poise, we think that since we don't feel how that person looks that we don't have patience. But patience isn't indicated by how a person feels. Patience is simply put, not giving up.
When a person runs a marathon, it's possible that they need to walk a bit during that 26 mile run. They may limp a bit. They may crawl a bit. And for the rest of their life they can legitimately say that they "ran" that marathon. Why is that accepted in the running community when they literally did not run the full measure? Because they didn't quit! In the same way, you are exhibiting patience IF YOU DONT QUIT!
Whatever you're enduring, whatever is causing you pain and suffering for a long time (ahem, "longsuffering") that suffering is not an indication that you "don't have patience." The pain means you're STILL IN THE RACE!
STOP saying, "I have NO patience." Words are creation. In reality you simply are anxious, not impatient.
We can learn the discipline of biting our tongue in our anxiousness. Similar to ancient days, before anesthesia, they might give a hurting soldier a piece of leather and tell them to, "bite down on it," as the medical staff inflicted a needed pain to give the soldier an extension of life. When we feel that anxiousness and desperation we need to also, bite down on it; our tongue, that is.
Scripture gives us instructions to help keep us in the race, enduring to the end.
Cast down imaginations.
Truly, this is our worst enemy. Satan doesn't need to do hardly any tempting because we conjur ourselves into failure. Our imaginations so rarely create hopeful scenarios. Our imaginations quickly leave us in a heap of failure. And crazily enough, these mythological ideas release real chemicals in our brains which continue into real depressive states!
Bring (Force) every thought into the obedience of Christ.
Christ is our way maker. God is the miracle worker who is able to do exceedingly, abundantly, above all that we ask, or THINK. (Think: imagination.) He's NOT however, a genie. He's a Father who sees how the present difficulty is teaching us how to handle yet another situation later, which will require more strength than the current trial. Today's trial is merely building your stamina to handle the future's success.
Cast your care on Him.
Another word for, "care" is, "anxiety." We must find places to pray. We must duck into rooms to release the pent up anxiety. We must allow tears to come while at His feet. We must allow ourselves to moan in prayer. The scripture says that when we do this the spirit is asking God for what our soul needs, because our brain doesn't realize what we need. Praying in the Spirit does WONDERS for every aspect of our trials.
Keep your eyes on the prize.
Christ was patient on the cross because he had his eye on the prize. He endured the cross. He despised the pain. But he was able to reach his success because he had a prize in mind. The relief and release is going to be a wonderful experience! Jesus has reward for his children who are longsuffering.
