Yeah seconding this advice. If you really want to help someone who struggles with this, long-term help / working them on strategies to avoid escalating mania & exacerbating it in the future is the highest impact form of help.

Don't agonize over how to handle the situation in the moment too much and don't take anything they say seriously or try to make any decisions, just keep them from hurting themselves and try to steer them towards medical help to the best of your abilities.
