I suggest you get tested for psychiatric diseases like Bipolar or depression. I used to have similar mood swings and a year ago I went into major depression. I consulted a psychiatrist and got diagnosed with Bipolar disorder and depression. The mood swings were due to Bipolar. Now after one year of treatment and still going, I am having less mood swings. Depression has pretty much gone away too. But general lack of motivation still persists.
