Over-worked

I think I am a little over-worked recently... having so many datelines to meet... I already a little bit don't care le... but... tt's not the problem... the problem is tt the wires in my head like a bit attached wrongly... having weird emos recently... can suddenly feel very sad for no reason then sudden feel very hyper... today even weirder... in the afternoon, out of nowhere, sudden have the 我很幸福 feeling... then after that suddenly feel very pathetic... lost... I also lost... although not very affected by these weird emos but juz have lots of question marks in my head... oso donno what is going on with me... haha...
