You will never get support or belief, so dont expect it.

Five percent of the people think, five percent think they think and the other ninety percent would rather die than think.-Mark Twain

Even if you make a full recovery and start playing the guitar like Eric Clapton you will still not get any support or belief. Perhaps someone can explain why people are that way. If they refused Jesus they will surely refuse you. ONly us folks here will support and believe you and that will be sufficient.

YOu should avoid DMPS tests as they are too dangerous. That only leaves a DMSA challenge test which needs to be done right. You might keep some hair samples but those are not reliable. In the end it will be how you feel that matters.
