I was puking for almost 2 hours, at about 12am I passed out and just woke up at 2 to my boyfriend on his lunch break. He works overnight at Wal-Mart and every night I cook him something to eat for his lunch. needless to say I didn't cook tonight because I was passed out and I feel so bad. Like that's the one thing I do every night and tonight I just couldn't. he wasn't upset or anything but I am one of those people who gets upset at myself easily for not being able to do something that has become routine to me. How do you deal with it when your emotional and feel this way?
