The best advice I can offer. If you aren’t American and still want to help, please make some donations (if you can afford it). The ACLU and the NRDC or Earth Justice are the things that are most likely to affect you outside of the US- the first is an organization of free lawyers working for the rights of individuals and groups whose constitutional rights are being hurt by the US government (including non-US citizens/residence; as a whole, they are the closest thing we have to a private non-profit that will go and stop a Trump dictatorship) and the latter two being environmental advocacy organizations, because a Trump presidency is predicted to have a terrible and irreversible effect on the environment.
I am so so so sorry guys. I am so sorry.
