Anxiety Help

Hi Everyone, I am looking for some advice and inspiration. My anxiety and depression have took a toll on my 6 yr relationship. My now ex has left back in October bc of the issues it was causing. We still talked everyday and would still come and stay on his days off. A week ago, I threatened to hurt myself. Police were involved and I was admitted to a mental facility for 4days. With this situation it has put any possibility of us being together to a stop. He still talks to me and came to see me a couple days ago. We cried and talked. He says I need to get help for myself and maybe we can be in a relationship again once I have helped myself for myself. I know it has to be for me but I am so scared that I have lost him. I am scared that he will not be there once I have found my way. He says he will be here for me now and wants to see me better. But I really need some inspiration from anyone who has been in or has seen anyone over come the situation and has repaired and healed their relationship. Please help.
