get sick because of yearning; being tortured by yearning; cannot bestir myself without you; Since we parted, my spirit has been out of my body; your not being here with me distresses me everyday; Not seeing your face, I feel depressed and listless; encounter trouble falling asleep at night because of my inability to erase the memory about you。处理方式太多了，“思念”和“疾”的表达逻辑可以说是无穷无尽，可以随意变化，有语境的话可以更具体贴切些，我随便编了一些，你看看。
