I need a pick-me up
Sure thing, what is worrying you so much?
I'm worried that my girlfriend will dump me for being insensitive
Maybe you should try to talk to someone else about it. Therapy is always an option, there is nothing wrong with it.
I would rather not. I think I am going to just try and chill out.
That's alright, you can try to calm down and relax now and come back to the situation later. When that's done, how about talking to your girlfriend about how you feel instead of just guessing around? It can probably just be a silly misunderstanding you can laugh off together.
