Feeling sick on and off for over 6 weeks

Not sure when to see a doctor for what’s like a cold that comes for a few days, leaves for a few days, and then continues again. I’ve never had this before. I don’t know if this is my body saying I’m just not able to fight off illness anymore or what 😭 it’s not the worst illness in the world, but it does kick me down a bit. I’m so tired of it :( not sure when to make the call to go see a doctor, which is mainly because I’m in between primary doctors right now along with my parents having to drive me and they always make me feel guilty for having to see a doctor more frequently than 99% of people
