It is shit OP. They don't care about you, and it's times like these that you find this out. It's happened to me too.
Time to pull back from them. Do you have any other friends who do ask you? If not, try to find new friendships to build on.
Oh, and to tag someone, either put the @ directly in front of their name, @fairycakesandtea7 and they will get an email, telling them they've been mentioned in a post, or put an asterisk * * immediately before and after the name (don't leave any spaces). This bolds the name (people also use it to quote) but won't send an email.
Don't feel you have to reply to everyone individually though, or it could get tedious, especially if several people are asking the same thing! 
Be aware, AIBU can be very robust, and there is often at least one poster, who will decide you're BU, and no explaining your view will change their mind, even if every other person in the thread says you're not. They just like being obtuse and antagonistic. Don't take it personally, it's best to ignore them.
Welcome to Mumsnet! I hope you're recovering well.
