Hey! Marcus wrote for himself, Meditations are a collection of phrases and notes he wrote on his diary.
It can be a good start as it may help you perceive and understand yourself.

Epictetus taught on the streets and his lessons are more about life in society, good and bad things, how we could behave to avoid bad thoughts and pain caused by our reactions.

I'd recommend starting with Marcus Aurelius. Anyway take care of yourself, too will find peace too.
