Another day in the lab and greenhouse. Terrible,again. Just an incident, but made me feel more depressed. I am used to do experiment under others` instruction. So problems come up one after another when I explore sth. on my own. I need to think over incident that might happen. I have to handle all the trouble at once with no time to discuss with my mates.This uncertainty of results brings me anxiety. Sometimes when i am about to get to sleep, I may suddenly recall a problem in my experiment and worry about how to solve it the next day. I donot like this feeling and have not the curiosity to dig out all these complex things~~~~I have no talent for experiment. I need time to acclimatize myself to it. After all , I still have three years to go.... Come on!!
