I need advice

I have been going through a lot of depression lately I haven’t been feeling up to doing anything I have no motivation whatsoever. Last week I lost my granny granted I haven’t seen her in a couple years due to me living in another state but I was very close to her when I did live close ‘ ever since then I’ve been going downhill . Im behind on so much stuff ‘ I really need help I can’t even go to my granny funeral! I don’t know what to do anymore ‘ I need resources I want to do better I want to be better feel better !
