You're not alone. I went through this earlier this spring. Sick for a month and a half, I was actually prescribed a third antibiotic and didn't end up taking it after all (toughed it out), but it was horrendous. I didn't feel like I was ever going to get better.

Many of my friends went through or are going through similar situations with illness this year. I think it's just something in the water.

With that said, I find I'm actually sick less often in the past 10 years (dx'ed for 1.5, but my neuro suspects MS for 6 years approx.). When I have been ill, I've been hit hard though.
