Well having it for 2 months I don't think it would be a bug. The stomach issues and inability to sleep could be way anxiety I manifesting its self. You should go see a regular doctor 1st though and make sure you rent having any digestion problems or something like that. As for it feeling like you can't stay conscious that happens to me often with my depression... I am just so tired I can't function.

Good luck, hope you feel better soon.
