Need help

My last sexual partner told me he had chlamydia a week after having sex so to get checked, I think went crazy and he told me he was joking since then I’ve become so paranoid and debating weather to book in with a doctor, however recently ive Been getting really uncomfortable down there so I’ve been looking, I’m finding lumps and bumps some are just bumps but some look like actual pimples which could be squeezed, I haven’t squeezed any as I’ve been googling and it says not too but I also had a really painful burn everytime I urinated, that has now gone by itself it’s just the lumps now affecting me, I can’t walk lay down sit down or even wipe after the toilet with out being in pain & cant shave my lady garden as it’s way to painful to touch,has anyone experienced this or have any help for me I’m too ashamed to got to the doctors😢
