Quarantine and depression help?

I'm from New Zealand and our country has been put on lockdown due to coronavirus. I live in a studio where I don't have anyone else to see. I asked some of my friends if I could come and stay with them during the lock down but no one said yes.

So I am stuck being completely by myself for the next 4 weeks. No human interaction apart from social media. I don't have my family here, or any friends.How do I survive this?
