Can you please pray for me?

Can you please pray for me? My fiance's mom is 46 and she had a stroke on Thursday. My fiance has autism and doesn't do well with change, but he also has PTSD and severe anxiety and his mom is his whole life. She raised him alone. Now her words are all slurred and she's forgetting words. I don't know how to help him. I'm afraid because I know that trials like this put relationships through testing and I just want to be able to get through it and support him as best as I can. I brought flowers and cookies when it happened and I have been cuddling him and checking in, but I feel so helpless.
