I've found quite a bit I have been able to use on this site and I'm glad I could give something back. Thanks for keeping the discussion alive.
I'll second the strategy of comparing treatment to chemo. I think I've called it chemo-lite or Jr before, in deference to the fact that I assume that as bad as this gets, I'm pretty sure chemo patients have it worse. That's what I've told myself on the worst nights when I literally feel like I'm dying. When it seems like any of the breaths I take could easily be my last I try to console myself- at least I'm not in chemo.
Don't be too quick to condemn your friends hopehere. It's a complex psychological process when someone hears one of their friends is ill. It's hard to see someone they might have known as a vital, energetic person get turned into a a shadow of themselves. Some people can't handle the emotion or are afraid they won't know what to say so they just avoid the situation.
Its doubly complex because it's such a mysterious thing you are telling them. If you tell someone you got in a car crash and lost a leg then it's relatively easy for them to comprehend the situation. They know what to say to you, they know what to expect from you, they know how your life will be different and know how your friendship might change. Lyme is so much harder to quantify in all those regards.
You should give at least some of them a chance to come around. You are forced to fight for everything that makes you the person you were while battling Lyme; it may be a struggle to maintain your old relationships as well.
