Have all the symptoms. Saw them building up but couldn't stop it. Insomnia, racing thoughts, impatience, irritability and splurging tendencies (avoided buying anything until now, don't know how long can I avoid it.), intense food cravings. Also down with a viral infection so body can't really keep up with the racing mind, which is soo frustrating  I can't really rest and can't do any work either. It just sucks soooo bad.
