Hey! Guess what?! I've had the second year blues too! I was feeling so down a few weeks ago, but it's better now! I go away with my friends from university, climbing and walking, a fair bit, and I try to arrange meeting them when I'm low... It helps so much to get out and away from the lab! Or just to have the next trip to look forward to. If you're at a University why not join one of their clubs? Lots of post-grads get involved in ours...
