What doesn't kill you makes you stronger

This phrase hit me once I done crying, walking back to faculty. This is a bad day ever that I had failed to get results of RE digestion. The bands are faint what else I should do if I was not allowed to do pcr? This is freaking damn bad!! I can't proceed without pcr u know?! Could I change supervisor or lab or seniors? Omg now it was too late thinking on this. I have tried to extent of tired to strive and struggle for results, que sera sera, but if so how am I suppose to hand in reports without data? How to make thesis thick enough?

This is driving me crazy cause I failed! I am useless! Once I was the top in the lab, now I was the worst I suppose. I was so afraid of presentation terribly ! Omg~~ but I never lose hope, hopefully I can get good one tomorrow=)
