Having such a big surgery is very tough and it is good to hear, that your migraine frequency lessened. I also think that mine are strongly tied to my hormone levels, because I have some problems there... Knitting or crochet during an attack is for me also impossible, only in the days before or after, when the headache (and other symptoms) are not so intense I can use this tool to distract me.
And the point you made about the connecting is soooo important. Often the issues themselves make it hard to keep up any regularity (friends, work, hobbies, driving etc.) and finding friends and compassion, new info’s and encouragement online is very helpful. <3
