Unruptured Brain Aneurysm

Hello! I recently found out I have a 4mm ACOM during a CT scan, waiting CT angio appointment, question is....live life normally? OK, to travel (fly), exercise etc. Can't get answers from doc, they say all this will be covered during pre-op which is weeks away and in the meantime causing me anxiety not knowing what I should or should not do. Not sure if I have symptoms, various headaches, mild, dull, various areas of the head, but have those often and for long time, and stuffy nose so assume its sinus. Any help is appreciated, suppose to travel in 48 hours. I read all this about rupturing and frightens me. Is it something that would happen suddenly or gradually from a leak. Help! THank you.
