Can you expect your SO to help when you really need it?

I am off sick for work-related stress for 5 days now. Today my workplace reached out to me, asking urgently rectify a matter from 6 month ago - I had to recall all data from memory, it was stressfull, and I also explained they investigated that case 4 month ago and they did not find any concern - my line manager apologised for not realising that it was actually a closed issue, and dropped it. But it really shook me and I found myself crying, shaking - back to square one.

I asked my husband whether he could take our son to piano as I did not feel I could drive.

He said no, as he does not like the rural road leading to the piano teacher's house.

I explained I really not feel safe driving. He insisted it is his right to refuse to help if he feels so.

I felt so let down. It is difficult to ask for help, and I feel if I ask my husband for help in this situation, he should.

I literally have no one else in the world, no live relatives to count on, no friends. I felt there is a disparity between: I am having my first (and hopefully the last) mental health related episode and him not liking that road to drive on.
