My understanding that you need N95 mask to protect yourself.

To protect others from you however, you probably just need to make sure you don't spit, and don't touch your face. A cloth mask could help with both. Gloves may also help (having something on your hand can remind you not to touch your face).

Doctors & other exposed personnel need masks to protect themselves. The rest of us likely mostly need to protect them from us.
