Hi Abby,
I don't think what you're asking about is petty at all. I'm not sure what I'd do though. Do you think the stress of going to therapy would be likely to cause you have problems noticeable to others? Or problems that you'll have to deal with consequences of in the future? I guess if it was likely to set me off that much, I'd more likely wait. But if not, either way could be okay... good luck with deciding.
