Positive Huntingtons Disease Test

My boyfriend (23) and I have been together for around two years now. I always knew his mom had HD and we’ve even visited her together before many times (we live about two hours away from her and his family)! Recently, my boyfriend and his two sisters decided to get tested for the gene. One sister tested negative, and his other sister and him both tested positive for it. My boyfriend has previously struggled with anxiety and depression (almost his entire life) and has had many panic attacks in the past that I’ve helped him through. The positive test has really pushed him into a deep depression, and he is self aware of it and talks about it with me, but refuses to talk to anyone or seek any help. Its almost at a point where I’m afraid to leave him home alone because of some of the “jokes” he makes about self harm. All of this is becoming a huge strain on our relationship and is pushing me into depression watching him go through it. I feel so defeated between being there for him/keeping him safe, and trying to keep myself okay through it all too. I feel I cant come to terms with the result until he’s okay and my mental health is suffering as a result.

What steps should I take to get him help? Should I consider getting him help in the first place, or is that overstepping? How can I process my own emotions about the result/our future together?
