I agree with the above poster–you need to do more research about what being a physician is all about. You’ve romanticized it. I strongly suggest that you do some job shadowing so you can see what the day-to-day life of a physician is like. You should consider also shadowing a nurse and a pharmacist too to get a feel for their careers.
BTW, advance practice nurses/nurse practitioners can practice independently and can provide basic routine healthcare services, write prescriptions, do simple procedures, manage common medical conditions like diabetes or asthma. Nurse midwives do nothing but provide prenatal care for healthy women and attend routine deliveries–all without physician oversight. Nursing is a challenging and honorable career in its own right.
Besides the careers you’ve mentioned there are dozens of other you don’t know about. Here’s a website to help you learn about other healthcare professions-- [Explore Health Careers](https://explorehealthcareers.org)
If you want to have the greatest impact on the lives of children–consider teaching. Teachers have a far, far bigger impact on the lives of children than physicians do. Or consider social work or public health. Those also have a major impact on the quality of life for women & children.
On to your question about Washington state. You can certainly do your undergrad in WA. WA has many fine colleges & universities. All of them will provide the coursework needed to apply to med school.
Staying in WA for med school is much more problematic. Admission to medical school is extremely competitive. There are no guarantees that you’ll be admitted to either of WA’s med schools. UW is extremely competitive for admission. It’s impossible to say if you will even have chance 4 years from now. WSU has a mission to provide doctors for eastern, rural WA --if you don’t fit that mission, your chances of getting admitted there are poor. Med school applicants generally need to apply to 15-25 med schools across the country in the hope of gaining one admission. If you want to be a doctor, you go wherever you get admitted. If you’re not OK with that idea, then you should consider some other career.
You should also be aware that completing medical training requires 3-8 years of residency & fellowship after med school. Unless you complete a residency, you cannot practice medicine or obtain a medical license. The chances of being able to stay in WA for that part of your education even if you do graduated from WA med school are quite small. (Fun fact: doctors are matched into residency programs by a computer program designed for optimal utilization of resources on a national level. IOW, you don’t get to choose where you go for residency.)
For pharmacy–you can do your undergrad in state easily. There are 2 pharmacy schools in WA: WSU and UW. Again no guarantees you’ll get admitted.
RE: majors
You don’t need to declare a major just yet. You typically don’t have to do that until sometime during your sophomore year.
Pre-med is NOT a major; it’s an intention. You can major in anything you want and still go to med school so long as you have taken all the required pre-req courses (gen chem, ochem, biochem, bio, physics, calc, stats, psych, sociology and English) My daughters have med school classmates with majors ranging from forestry to engineering to music performance to theology to business. Neither of my daughters (one a medical resident, one a med student) majored in bio.
Pre-pharm requires similar coursework to pre-med, but exact coursework requirements vary from pharm school to pharm school.
If you want to see if yo have the academic chops for medicine or pharmacy or many other healthcare careers, take intro bio, and gen chem your freshman year. In the remaining slots, add calc 1, English comp/writing, psych or soc, and some other courses of your choice
