20 years old & afraid I've lost hearing from a few gun shots?

Hey everyone. Over the course of the last 6 months, I took around 8/9 shots of .40S&W, and just this past Wednesday, 3 shots of .380ACP with no hearing protection (some of the times I did have a hood up though). I have experienced "fullness" in my ears since then, but it is going away. However, when I laid down Thursday night, I noticed a ringing in my ears & I'm afraid it can be Tinnitus. I did some reading & I want to cry. I've always used earplugs, but these few times I just made a stupid decision. I know that gun shots can & will destroy your hearing if unprotected, but I had no idea that just a few shots can. I mean, you hear about soldiers having Tinnitus, but that's after battle & hundreds (if not thousands) of rounds fired. I have a hard time believing & accepting that I destroyed my ears from these few incidents, and very few shots. Music is my life (Rap, Hip Hop) and I'm worried I'll never hear the beats the same way again. Is it as serious as I'm making myself believe it is? I also have severe anxiety & stress, which isn't making things any better. I'm 20 years old, and I can't accept that I did my hearing in from a few shots, I just can't. Please tell me I'm worrying over something that will pass. I do have a doctor appt this coming week, I'm just trying to find some comfort in this & reassure myself everything's going to be alright. Thank you guys.
