YOu can check outlistings of Buddhist sanghas in the Vietnamese zen tradition of THich Nhat Hahn. THey have groups worldwide and have some online sanghas, or groups. It has helped me immensely! Also, there are vipassana meditation groups, Shambala Tibetan Buddhist groups, hindu, yoga groups. I would start with simple breathing meditation of mindfulness meditation. Even youtube has some free videos on this type of thing.
