When you said "being a doctor doesnt seem fun anymore" I had figure you were dropping out of medical school or were going to take an extended break.
My previous job was in one of the top medical schools in the country and I would help Medical Students plan and "match" for their future residency positions during the 4 years they had with us. When graduates are trying to "match" they are basically in competition with other graduates from all over the country for open positions. Taking extended breaks from medical school, once you start, "can" reflect negatively during this process so it is best to avoid if at all possible. Even situations like pregnancy were discussed with my female students because of possible time away from classes.
Since you have not started medical school yet, taking a break from a BS or even an MS degree is not going to have any long term impact in my opinion.
Following up on what Marmaduke said here:
marmadukeGRYLLSI went the drop out route with 2 semesters to go about 3 years ago and holy fuck do i wish i stayed. Starting back up in the fall to finish. Think very carefully about this before you decide. Its 10x harder to go back once youre out in the real world working 40+ hours a week.
I am not advocating you to drop out of school in any way but you do have viable options. I agree with Marmaduke but you personally have advantages over other types of students because you live at home and don't have the huge stress of money to pay rent/mortgage. If you had that money issue, then you would need your job more than you need school. In your current situation, getting a job and then quitting that job to restarting school can be an overnight process when the time is right.
