Has anyone else ever put off seeing a GP?

I'm not very good at articulating myself in person so I try to avoid interacting with people. For approximately one week I've experienced heart palpitations when asleep, struggle to fall asleep without jolting awake, general breathlessness, constantly having to yawn or take deep breaths, and an assortment of other strange sensations and pain in my heart and with my breathing that I'm unable to explain or describe. I'm experiencing one such sensation as I type this on a train. Because I'm not great at explaining things I've avoided seeing my GP out of concern I wouldn't adequately explain my symptoms and thus be a waste of both our time. Have you ever put off seeing a doctor? Edit: the conventional wisdom is to call GP, which I'll do at some point. I'm able to live my day-to-day life despite the symptoms. They're just a slight annoyance.
