How to tell your mom you

Hi! I need advice on something.

Ive been feeling really down lately, I feel empty and tired all the time, nothing excites me or interests me anymore. Ive had lots of moments like these in the past, but this time its way worse.

Ive tried telling my mum about how I feel without actually telling her I think I have depression because I know that if I did I would end up crying and I dont want her to feel guilty. Shes been doing her best with me and my sister ever since our dad died.

Nonetheless, I feel awful. Ive told her I feel sleepy and tired all the time and I dont want to do anything anymore, but she dismissed it. Ive always slept lots, so I think she doesnt take seriously the fact that I have been awake for like literally 5 hours a day for the past few days. I really think I need help but Im scared to flat out tell her.

Thank you in advance 💓💓
