My experiment didn't work. Again.I'm so tired of this. Doesn't it seem like I'm always moaning and complaining? But that's because that's how I feel. I'm always in the lab earliest and leave the last. It feels really miserable to work in solitude for the entire day and have things keep going wrong.Nothing seems to work. I keep repeating but I don't know what is wrong.

Does this mean that I'm not cut out for research?

Ok, I need to stop worrying about this. There's nothing I can do before my mentor gets back. O need to start in my progress report. Period.
