to me it sounds like you´re stuck in the well-known 'burnout syndrome`. in one of your earlier posts you mentioned that you cant afford to take one day off - thats crap imho. take a friday or a monday off, enjoy a prelonged weekend and stay away from work and absolutely everything that has sth to do with stocks/stockmarket/etc....give yourself a breather, man!
i suffered from exactly the same problem and went off for holidays. as i returned i had a lot of the 'fresh energy' you mentioned in your last post. do yourself a favor!
i can imagine that at the moment it´s kinda hard to take a day off as you became a team-leader recently. but in the longer run you probably wont be ta big help or that much supportive for your team if you cant give >100% just because your batteries are running on 85% only. think about it.
take care,
