Anyone has knowledge of any volunteer projects that are accepting volunteers without being a doctor...or highly educated?

I am looking for a project that is not just for a few weeks where you have to pay insanely expensive flight tickets, but a project i could dedicate some years to.

I just can't get a job to earn money, i don't have the motivation for it, if i do something i want it to be for a bigger purpose.

If anyone knows of anything please let me know, its pretty urgent...i feel i will sink into a deep depression if i don't start acting soon >.>.
