How To Mentally Recover From A Significant Injury
Be Realistic

Anyone who is recovering from an injury should avoid being overly optimistic as well as pessimistic. If expectations are too high for how quickly one will recover, they will end up feeling even more frustrated than they would otherwise when things do not go as planned. Injuries come in different forms, so the severity will depend on circumstances. An injured person should make as much of an effort as possible to recover, but they should not willfully ignore advice that they do not wish to hear as there needs to be maturity when handling this type of situation. Recovering from an injury can be a gradual process, and there should be no urge to speed up the process unnecessarily.
Accept Life Changes

Any significant injury is going to affect one's life; the main question is just how much impact it will have. A particularly debilitating injury can mean one has to stop playing a sport or they might not be able to move around in the same way they are used to. This does not mean that life is over and they will never be able to live remotely normally ever again. Instead, it means they will have to make some adjustments to their life that could be difficult to adapt to or accept. For an easier transition, one must be willing to accept that things could be different from now on.
