Lady Gaga needs to be shown love after Joanne World Tour cancellation

Today it was announced that Lady Gaga has cancelled the rest of her Joanne World Tour. The European leg of the tour was already rescheduled back in October due to Gaga's severe pain from Fibromyalgia, and once again her pain means that she is unable to complete the rest of the tour, 
I can't begin to imagine how Gaga must be feeling right now. Both her physical pain and the emotional pain of having to suddenly end a world tour must be overwhelming. She is one of the most hardworking artists in the music industry today, so to see her not being able to do what she loves because of such a horrible illness is heartbreaking to see. I was due see Gaga tomorrow in London, which I've been looking forward to for a year. Of course I'm devastated. This is the first Gaga tour that I will be missing. But how can I be angry at her? I've seen a number of people on Twitter being both hateful and angry. and I think that's disgusting. To hate on such a hardworking artist who puts her music and fans above anything else is heartless. Gaga can't help having an illness, and certainly can't help the amount of pain she is in. 
People, like myself, who had their tour dates cancelled obviously have a right to be disappointed. However, what they don't have is the right to be nasty with their comments. If these people really are fans, they would understand that Gaga's pain must be severe to make her cancel. 
The pain that Gaga has to deal with was also shown throughout her Netflix documentary, Gaga: Five Foot Two. The whole documentary focused on her battle with Fibromyalgia leading up to the Super Bowl. The viewers could see just how much pain Gaga was in, but also how strong and brave she is as well. So what gives people the right to send so much hate to her?
I hope that this situation not only raises awareness for invisible illnesses, but also makes people truly respect Gaga and the battle with pain that she has to go through every day.
I've been a fan of Gaga for 10 years now, and there is no one I find more inspiring than her.

​I'm sending all my love to Gaga, and I hope she takes as much time off as she needs to properly relax and start feeling better.
