Addiction to pain meds is a bad thing because your quality of life will always be reduced. Dependence on pain meds can be acceptable, if quality of life is improved with them.

You need to concentrate on your own acceptance that RSD/CRPS can be a long term, life altering, medical condition. Your family and friends opinion of your health is their issue, not yours, and you need to stop focusing on it. If they stick around, they'll figure it out, and if they become less involved with your daily life, than you'll need to adjust.

Even those that have supportive family members in the early stages, often find that they are lucky if they have even one or two people they can count on long term, in any type of meaningful way. You can help: by actively learning to adapt, seeking out a therapist to learn how to adjust, and not having any unrealistic expectations of others.

From your postings of how you're struggling physically, it seems unrealistic that you can get through your RN testing. And if by some miracle, you do manage to get through it, the result might very well be that it undermines your SSDI claim. This is an example that would very likely confuse your family and friends, as well. If you can't accept the new limitations your facing, how can you expect them to?

What happens with RN candidates that are wheelchair bound, btw? Are special accommodations made for them? If you were in a wheelchair, could you manage the testing more easily?
