1) You need to see an adviser. Because of your mental status, you may be eligible for a disability resources adviser. Trust me when I say that the health professions advisers are essentially useless. They have way too many students to manage and they are not up to date with all of the requirements for pharmacy schools - they mostly focus on medicine.
2) You are going to have to improve your study habits hardcore. The chemistry labs and physics labs are intense and a whole lot of work for just one credit. Be prepared to spend an incredible amount on lab reports with lazy, incompetent group partners (not ALL will be like this, but remember not everyone gets into med/pharm school).
3) You need to figure out a schedule that is manageable. Balance your schedule with a lab, some gen ed requirements, and a class or two for your major. For MWG and UA, completing your labs at the University isn't essential, but strongly preferred.
4) The major itself doesn't matter. In my class we have Psych majors, Nutrition majors, poli sci, engineering, and many more. If you have trouble maintaining focus studying or if it takes you longer to learn something because of your psych meds, then you are probably going to want to pick an "easier" major. Therefore, stay away from biochemistry, microbiology, and psychology, all of which are strong programs at ASU. You could go for some other social science (sociology), communications, or a general biology degree. Either way, you really need to get in to see an adviser, ASAP, and IMO you might want to disclose your issue to the school because you may be eligible for additional resources... just saying.
5) The bonus of picking the "harder" majors is that you could get into a research lab much easier, which is a great experience and adds to your application. Furthermore, once you are in pharmacy school, if you are planning on joining a research lab at UA, the PIs seem to prefer students who have at least SOME experience in a lab, even if it is minimal. But, being a part of a research lab is not essential to the application. It would be beneficial if you are not as strong in other areas.
6) Unless you are an URM and/or a strong applicant, UNM is probably a no go. Seriously. Although, they do prefer students from bordering states before all other states.
7) Join the pre pharmacy club. They will have practice PCATs and mock interviewing throughout the year. You should be active in EC's. UofA likes that.
