Hi, I'm looking for some advice/resources as someone with a partner who's anxiety is steadily worsening. I hope none of this comes across as me being condescending, or that I think I can magically "fix" the issue, I just want to be doing everything I can to be supportive. 

My partner has had anxiety for a good few years, sometimes very mild and other times much more prevalent in their life. They readily admit they have anxiety and that it's a problem, but have never really tried (that I know of) to tackle it directly.

I do as much as I can to help in ways that are possibly more indirect, i.e. housework, childcare etc. to relieve as many stressors as possible in our home life. I guarantee I'm not perfect but I genuinely try. Recently, the anxiety has been consistently high and I feel like we've reached the point where we need to actually find some strategies to take on the anxiety itself together. It's one thing acknowledging the existence of the anxiety but it feels like time to actively try to do something directly to help.

What are some ways I can go about having the conversation? I realise everyone is different and the last thing I want to do is make things worse by bringing this up. I worry about it being seen as cornering them, making them feel like they're the problem or that I'm pressuring them to be different when in reality it is very much us Vs the anxiety type of discussion. I know my partner well and it feels like we're close to the start of a dark path that I'd very much like to avoid. 

Are there some beginner's guide type resources out there that would be worth picking up to get us started?

Any general advice on how you've supported or been supported by someone?

It isn't an ultimatum type of situation, our relationship is extremely strong, I just fear that their mental health is in a bit of a decline and want to help in any way I can before things get worse.
