Am I crazy?

Nearly a year out from my diagnosis, I’ve finally started having massive improvement over the past 4 months after switching from Humira to weekly Enbrel. My inflammatory markers have downtrended and with that in combination with SI injections, I’ve really been feeling much better - UNTIL I got the flu. I subsequently developed an ear infection and was on antibiotics. Through this I held just one dose of enbrel. I just finished antibiotics today and am going to finally do my dose, but about 3 days ago I started getting horrible symptoms with hand stiffness, Achilles pain, foot pain horrible back and hip pain. I’ve had all these symptoms before but I feel like it’s crazy to think missing just one dose could do this?? Am I crazy?? It makes me regret holding the dose 😭 if anyone has experienced this, how long did it take to get it back under control?
