It's not going very well

So I haven't been studying, at all...I'm disappointed in myself. I don't even have a good enough excuse other than my health problems slightly getting worse lately. I have lost some of the motivation that I had right at the beginning of the year and its getter harder and harder to study when the list of words is endless and I have to spend a long time reviewing them. I have only just begun studying Chapter 7 and I am supposed to have finished it by now :S I have learned the vocabulary and I am going to begin the grammar tomorrow. It seems like I'm forgetting so much of the grammar though, and I keep excusing myself for not doing anything. I can only hope that I get motivated soon so that I don't give up.
