Am I being too clingy?

So I just got the news this morning that I might be terminated from my job. I kept my cool in the office but when I was in the rest room I nearly lost it. I called my boyfriend and asked if we could meet for lunch because I wanted to talk to him. He said no because he needed to sleep and I insisted. Still a no and I conceded even though I was not happy about it. He hung up on me.

I texted him that I was thankful that he was there for me when I needed him and that I appreciated that he obviously cared for me in a sarcastic way.

He told me I was being unfair because I woke him up and yet he was the bad guy. I ranted about the situation because I couldn't take it anymore and he told me to stop moping and to grow up and stopped replying.

Now the question is, am I being too clingy for wanting to talk to him about my problems even though I know it will interrupt his sleep? Am I a bad girlfriend for waking him up just to talk to him and let off steam?

Or am I just over reacting about the whole situation?
