The breakup.
Thinking on your feet was one thing, trying to back it up was another. There's nothing worse than a breakup. Sometimes you really wish you really didn't breakup, other times you're thankful. Breaking a promise by breaking up is also horrible.
Depression ensued. Trying to fix everything back together again didn't work. Trying to forget on demand was bad. There were no alternatives besides crying every night to sleep and being all hunched over during school. Not talking to the person you just broke up with was also bad. Being told you're not like minded hurt.
And you stay there. For 8 months.

Then one day you wake up. Your tears are gone, you manage to smile sometimes. You talk to your friends again. You hang around. Life, though quite damaged, doesn't seem that bad after all.

I miss the old. Before the breakup, it was bliss. There was never a sad moment. Though, I must credit those 8 months of nightmares and depression. They taught me alot. It helped me mature. So, I have to say both. New and old is good. It's a learning process.
