How do you know when you're asking too much from your partner?

Tonight I was feeling really lonely and depressed, and I needed comfort and love from my boyfriend. He's a morning person and I'm a night person. He fell asleep on the phone, and I started to get upset. He did eventually wake up and told me to "Stop whining" in kind of a mean tone. I interpreted the whole thing to mean that he didn't care that I was upset, didn't want to help me, only wanted to go to sleep. This all happened around 12:30.

I used to be worse about picking fights after he fell asleep, but since they put me on Prozac, I've been doing a lot better. This was the first one since they put me on prozac, a little more than two weeks. I also felt like this was completely different from before prozac -- i wasn't mad, I was simply sad and lonely, and needed comfort, and then really hurt when he got mad at me for whining.

Is it wrong for me to expect comfort from my boyfriend? Am I too demanding? What should I be doing differently? Should I learn to deal with my pain and emotions by myself?

I am in therapy.

What do you all do when you need emotional help at night?

Thanks ahead of time for your time and help.
