CurfewX has given you the answers you need about HIV. The only thing I can think to add is that you should probably get a COVID test. Your wrote "......I met many people around shaking hands where possibly their sweat could have touched my cut and also one guy whole talking his saliva fell in my eyes ......" Certainly sounds like you're not following ANY of the recommendations for the pandemic. CurfewX DID advise you to see a doctor about your non-HIV related symptoms and I couldn't agree with her more!
The only risks for HIV transmission in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles.
It is NOT POSSIBLE to get HIV from any wound that does not require urgent medical attention in order to prevent potentially fatal loss of blood. It is not possible to get HIV through your finger at all
See a doctor about your non-HIV related symptoms.
