Depression in new relationship.

Hello everyone,

I am so grateful to have found this forum. Reading your stories has already brought me comfort. After about 6 months being with my new partner he has suddenly stopped getting out of bed, answering phone calls and messages and participating in life. He's not even going to work. He is still eating and I don't believe he is suicidal, which is obviously a huge relief but I'm really struggling to understand how to help him? It is so early on in our relationship I'm not sure how to navigate this and am feeling horribly isolated. It does not help that I suffer from anxiety myself. My partner doesn't seem able to communicate anything right now so trying to navigate this with him feels impossible. He is generally incredibly stubborn which seems heightened right now. I'm hoping someone here can give me some advice on how to talk with him? I'm trying to be patient and encouraging without being overbearing but it is so easy to become deflated myself.
