The body you have, no matter what its issues are, they are not who you are. Thankfully, you are immortal spirit. You're just using this body temporarily as a vehicle to interact with the world.
You've had other bodies of various kinds. Memory of that fact would immediately help you to look at your current body as not a fixed part of your identity, but just a 'house' that you temporarily live in.
You have attributed various properties to your sense of self based on the body you have, how it looks, what color it is, how it moves, what its problems are, but none of those things really are to do with who you really are.
Just because you, or your loved ones, are showing up IN a body, doesn't mean you or they ARE a body.
If you could keep in mind that you are not a body and "no-body" else is either, then you'd see that it's kind of funny how we all keep going around acting as though what applies to our body applies to us.
We groom our body, decorate our body, look at our body in the mirror, do weird things with our body, look at other bodies, notice what other bodies are decorated as, and generally speak to other bodies as though they are people. But it's what's inside the body that gives it life - spirit - which without it the body would be just an empty, lifeless host.
This is part of learning to see yourself and others as Christ. Christ is not a body. Overlooking the body and not being distracted by it is part of forgiveness. Not regarding people as bodies is part of forgiveness. Not identifying yourself as a body is part of forgiveness.
At some point you're going to stop using this body, probably, unless you somehow convert it into a higher form, and then when you stop using it and carry on your way, you'll recognize how it is not who you are.
It's like putting on some clothes and then starting to believe that you are the clothes. It's easy to do, given how intimate you are with the body and how closely it seems to match your every intention. You are creating it, after all. But it's not your self.
Almost everyone in the world remarks about how 'you' look, what 'you' did, where 'you' went etc... really all referring to the "hero of the dream" - the exalted body which everyone is worshipping. The body is a false idol, and just an instrument to use temporarily.
It is by overlooking form and recognizing/knowing the true nature of your identity and the identity of others, not confused with bodies, that miracles are possible.
Miracle principle 20: "Miracles reawaken the awareness that the spirit, not the body, is the altar of truth"
Miracle principle 42: "A major contribution of miracles is their strength in releasing you from your false sense of isolation"
Miracle principle 44: "The miracle is an expression of an inner awareness of Christ and the acceptance of His Atonement"
Miracle principle 50: "The miracle compares what you have made with creation, accepting what is in accord with it as true"
"I am not a body, I am free" - ACIM
Quote: "Freedom must be impossible as long as you perceive a body as yourself. The body is a limit. Who would seek for freedom in a body looks for it where it can not be found. The mind can be made free when it no longer sees itself as in a body, firmly tied to it and sheltered by its presence. If this were the truth, the mind were vulnerable indeed! "
