For that kind of money, I surely wouldn't care about recoil, because the gun wouldn't get shot enough for it to matter!
My 13yo is quite a bit smaller than you are. He is not able to handle that level of recoil, or hold up a rifle that would make it tolerable. That said, I think that if you want to shoot it, you will figure out a way to make it work. My son has a number of other choices in firearms, so we went a different route.
Pain is pain. It is not mental. I hear a lot of people espousing the opinion that recoil is mental, and I can't imagine what would make them think that. Recoil can leave bruises or worse. That isn't mental, it's not a figment of your imagination, it's a physical reality. Proper technique and mental attitude can go a long way toward mitigating the effects of recoil, but they do not turn the physical reality of it into a mental exercise. That said, recoil isn't something to be terribly concerned about in normal kicking rifles, but it is something that must be dealt with.
Besides potential injuries (bruising up to separated shoulders and nerve damage, in the wrong combination of shooter/weapon), pain also causes flinching, which destroys accuracy, so if it hurts, don't just say you handle it and put up with it. Figure out a way to make it not hurt. Technique-wise, hold it tight to your shoulder, inboard of the joint. Recoil pads, worn or on the gun, can help. Lighter loads in the same caliber, or a lighter caliber, or a heavier gun, are the other things people usually do to find a tolerable level of recoil.
If you end up with something besides a .30-06, don't worry about it. I'm a lot older and heavier guy than you, and I rarely shoot anything that kicks that hard because I just don't like it. I can shoot them, but I get a lot more enjoyment out of "sissy-kickers", as Kachok terms them.
Good luck!
