If this is in the wrong place I apologize.
No, it isn't.

What I need help with is finding the best resources in books, forums, blogs, websites ...
This is the easy part to answer:

you have found the right place to be taught math and physics!
Now, to the difficult part. Astrophysics itself is a large field and it touches many other neighboring areas of physics and other science. So like any of such questions: Where are you at and where do you want to get to? I have a bit of a feeling this could be quite a long path ahead, but I don't know for sure.
So let me again answer the easy parts:
Here is a collection of useful links about self study, mainly from our insights blog:
https://www.physicsforums.com/threads/self-teaching-gcse-and-a-level-maths.933639/#post-5896947
I think they all contain good tips despite of individual differences, as in your case astronomy. Just pick what you think it's worth reading.
The next easy answer is: Make use of our homework forums! If you have specific questions to statements or need tips for exercises, and I assume these will be the majority at the beginning, that's the place to go. Just fill out our (automatically inserted) template there, and especially the third part of it, where we ask about your own efforts so far. Please do not write "no clue", as this won't be accepted. Instead write how you tackled the problem before you made the trouble to write a post.
Now that the easy things are answered, I'm back to the question: from where to where? Basically the amount of physics determines the amount of mathematics. They are closely related and you should know, that you cannot read good textbooks about physics without a decent amount of mathematical knowledge - and the more detailed physics will get, the more sophisticated the mathematical tools become. Thus the question form where to where is accompanied by the question: how deep? School mathematics and a good telescope will get you were Kepler had been, Einstein and black holes involve a lot more.
