Do you think my family knows?

I get sad a lot (don't want to say depressed because I haven't been diagnosed) but the day before, I couldn't even get out of bed.

Today my uncle and grandma were in my room and they woke me up pretty early. My uncle said "good morning M/N. we woke you up early to see if you were okay and everything."

Do you think he knows? I do have marks on my arm but I gave them an excuse months back. I haven't hurt myself since then and don't plan to.
