Should i be worried i turned 12 yesterday and scared i might have aids although i have no idea of symptoms

You : You can get aids only a few ways: you can be born with it; you can get it from blood transfusions; you can get it from sharing needles (iv drugs, tatoos, etc), and you can get it from sexual activity. You can't realistically get it from sharing eating utensils, touching items previously touched by a person with aids, or being in the same room with someone who has it. If you had been born with the HIV virus, then your mother would also have it. Do you have any reason to suspect she has it? If so, then the two of you should definitely talk about when she was exposed, and you should probably be tested. Going undetected for 12 years after being born with HIV is pretty unlikely. If you have gotten a blood transfusion, there is a risk, but it's pretty small. Blood donors are screened and donated blood is tested before being used. Still, it can happen, and if you have had a blood transfusion in your life then you may benefit from testing. If you are sharing needles or are involved in sexual activity, then you are certainly at risk. However, if you are doing these things at the age of 12, then you are clearly in a dangerous environment and are at risk for a lot of things. If so, the i would strongly urge you to find a child welfare agency in your area and get help right away.

AIDS risks: AIDS is a dangerous disease & careful avoidance is most helpful. AIDS can only be contracted through sexual interactions with another person, wherein exchange of blood or genital tract secretions occurs. Sharing needles is also a risk (drug use). Kissing, sharing from cups, eating with same utensils, hugging are not going to lead to HIV/AIDS. Best to talk to a responsible adult about all this.
