HIV does not pass by holding hands or by a person cooking or serving your food. The best way HIV is passed is by unprotected vaginal and anal sex or by sharing needles when injecting drugs.
There are no symptoms that are caused by just having HIV. The symptoms people get with a HIV seroconversion illness are common symptoms that can be caused by many different conditions, for example the common cold. Just treat the symptoms as a reminder you are concerned about what happened and it would be good to go for a HIV test.
With what you have described you have no reason to be concerned about HIV. First you did nothing that could transmit the virus and you had a negative HIV test at 11 weeks.
I have noticed that feelings of guilt can make people think the worse. I wonder if you are concerned that you were in a red light district or holding another woman’s hand.
Sometimes it can be difficult when you are in this situation. Your mind says that everything is ok but your emotions give you the feeling of worry.
Sometimes working on the emotion rather than thinking about it can help. Whenever you feel worried just remember it is about the emotion and focus on the information your negative HIV test has given you that you have nothing to worry about.
It may be helpful to find techniques which help you control your emotion for example deep breathing.
