I've done so many bad things in my life...oral, , shared toy,..I've had no symptoms...?

I've made many mistakes..through all of those things, I've never had any pain, sores, swelling, cuts, bumps, etc, after.. And neither did my partner. The thing I'm worried about is life. I'm getting tested Tuesday and I'm really scared.. I can't eat, I can't sleep, I'm beginning to starve myself. I've only done these things once unprotected..I never had l . But the toy was unclean but I didn't use it seconds after the person last to use it. It was a few days after(my guess). It was a metal toy too. I know I don't have Ghonnorea, Chlamydia, , or anything like that because symptoms would've shown considering the and happened over a year and a half ago..and no bodily fluids were transferred into my body ever. The 1 guy I gave oral to and did with was 1 year younger than me(13), so I doubt he had any othr . Plus I knew him and his family quite well. Could I possibly be clean?? The vibrator was in my for about only 1 minute..but should I not be so worried and concerned? I feel fine today, but I am not feeling too well lately. That could be from being so paranoid. Do you have any help that could be useful to me, so I won't be stressing so much? Also, after I used the toy, I took a shower and cleaned my genital and areas really well. I don't know if that would help but I'm hoping! Please help! Suggestions please??
