I think this misses the bigger picture a little. Given infinite time, everything that can possibly happen will eventually happen. Presuming that there are in fact some circumstances under which you would kill yourself, you only need to consider the likelihood of them occurring. If most other causes of death have been eliminated, then the only thing that could stop you from eventually killing yourself would be if you died by some other means before that happened.
