肯定有问题啊.
even though首先应该是分开写的,他们的意思是：尽管.是表示让步,你的句子里是表示递进,肯定不可以用even though; 而是用even.
except our homework最好放在句首,可以使句子平衡,不然的话,后面部分东西太多了.
如果要用myself,主语最好变成I,保持一致.
整句话最好是：
Except my homework,i am too busy to care for anything even myself.
How busy i am.
如果要用WE做主语：
Except our homework,we are too busy to care for anything,even ourselves.How busy we are!
