What can you do if you want help committing suicide, but you live in a state (all but Oregon) or country where assisted suicide is illegal?  Travel to Switzerland:

From the start, Mr. Minelli [founder of Dignitas] has kicked up controversy for his willingness to help foreigners die. Most groups in Switzerland don't assist foreigners. Dignitas only helps foreigners. The number of foreigners Dignitas helps each year—132 in 2007, compared to 91 in 2003—has increasingly left the Swiss uncomfortable with the country's growing reputation for "suicide tourism." As of the end of last year, Dignitas had helped a total of 1,046 people to commit suicide.

I do not see a convincing reason for bans on assisted suicide.  Informed consent rules are reasonable, but that seems sufficient to me.
