It's unfortunate, but most people just don't understand autoimmune disorders or the impact they can have on your life. That is the hardest thing to accept. The truth is though, that if those women cannot be understanding and stick by you, they were not true friends to begin with. Now if you had cancer and a bald head, you'd have more empathy than you could handle. There isn't much you can do about it other than let it roll off of your back and move on.
It's normal to mourn the loss of your body and your health. It's hard to give up the things you could once do and the things that you loved. I won't say that everything happens for a reason because it's hard to believe that when bad things happen, but it can show you other things in life that you may have been missing. You can choose the path you take. Every day when you get out of bed, you are choosing to live and go on. That is great! You have to find new purposes to your life even if they are not what you thought they would be. You have to find new things to be happy about and flip your perspective. Like I said earlier, anytime I start feeling down about it, I make myself feel grateful that I didn't have to deal with all of this in my 20's. There are young women (and men) who have to get through a
whole life of missing out on things and struggle to get through the days. I have had many good years and I am thankful for that.
When I was diagnosed with Lupus, a well-meaning co-worker gave me a card. It said "This too shall pass". I felt like she slashed me with a knife because no, this will never pass. I then decided to give that new meaning. I decided that it meant that the feelings of anger and sadness will pass. For the most part, they did. Self-pity only pushes people further away.
When I was diagnosed, I had to keep going at work and we were so busy, I was only pushed harder. The stress was enormous and I could barely keep up. Side effects of meds left me stuck in the bathroom for long periods and ha ha, we all laughed. Was it really funny? I was injecting myself with chemo for over a year but because it wasn't cancer, no one really understood. I showed up every day no matter how sick I was because it was expected. Then my co-worker got diagnosed with breast cancer. I love her, she is my friend, but there I was pitching in for a lovely basket of goodies for her and having lunch in her honor. No one was laughing. After six weeks of radiation, she got remission and has been ok since. I'm the one who had to stop working and give up most of the things I love to do. It's just the mindset of the people and there is nothing you can do about it.
Here is an article that talks about that very thing. You could consider seeing a therapist to help you deal with these feelings. Dealing with isolation on your own can be difficult and it never hurts to get help when you need it.
