Am I over reacting?

So normally my boyfriend calls me at least 1-3 times a day. We have maybe a 5 minute conversation, but that's normally because he's busy.

He's in job corp and came into some money, and for the past three weeks he'd go on weekend leave to go drink. Last week he said it was going to be him and nine other guys sharing a hotel just to drink.

Then when he got back to campus he called me Monday, and then Friday and told me he got stung by a bee Thursday and spent the night at a hospital (he's allergic to bees, like Really bad) he said he wasn't feeling good and he had to go and that he'd call me back because Friday everyone basically has free time after 5. But I didn't hear from him all weekend, so I called campus because I was worried about him and they told me he left for the weekend?

I called his cell which he always brings with him, and it just went straight to voicemail. So I called the campus again today to check and they said they'd let him know to call me back, and he hasn't.

It's frustrating because idk if he's ok, and we were going to make plans for me to go see him next weekend and I haven't even heard from him. We've been arguing a lot lately and I'm worried he's going to leave me. He tells me he cares about me, we've been together for 5 years, and he says he wants us to work out but I have too much anxiety and it causes too much stress and arguments on our relationship. Idk what to do.
