Islamic Ruling on Returning from Hajj and still having some Rituals to Complete

I was in Hajj, stood at Arafat, spent the night in Muzdalifah, performed the Jamarat ritual (stoning), and shaved my head. However, I was ill and still is, and couldn't complete the Hajj by performing Tawaf al-Ifadah, Sa'i, and Tawaf al-Wada. Upon entering the state of Ihram, I made the stipulation: "O Allah, I shall be free from Ihram where you detain me." Afterwards, I returned to my home country and Iam now ill and unable to travel to Mecca. Am I considered in state of Ihsar (Obstruction)?
