Help me

I'm barely 18 years old, I'm from Venezuela, and I don't know what to do, I went to the doctor because I had sex with an unprotected boy, my doubts grew and I asked him if he had any disease which he denied and called me crazy, then my doubts began to grow, I began to feel anxiety and panic attacks, and I even thought about committing suicide, I went to the doctor and the doctor told me that it was normal, but I just had to be more careful, I have a terrible fear because I don't know if I got infected with something, I did some tests and they came out negative, but I still have doubts since it was my first time, HIV, has a window period and I think it was what infected me, I spent the little I had and here in Venezuela the public hospitals do not offer where I live in my locality the option of free exams, I am feeling ashamed and I am depressed
