Impacting my mental health

Hey all, I’ve never really dealt with ED up until a little bit ago. It’s happened in the past but it’s been easy to get out of my head. Recently, it’s happened multiple times in a row. Not being able to get it up. It is impacting me so much that I do not feel like myself anymore. I have a long term girlfriend who is also feeling the impacts. I don’t know what to do anymore. I am so anxious. Any advice, words, or anything at all would mean so much
