my 3.1 sgpa is going to plummet. like drop like crazy
Look I'm applying this upcoming cycle so maybe I'm "doomed" too, lol. But I'm a non science major applicant too (cGPA=3.6, sGpa=3.4, would have been 3.55 with grade replacement), so I can kind of relate to your plight.
I didn't do great the first few science classes I took in college.. dropped o chem 1 once.. two C's in both gen chems.. did well in bio but those classes were always easy for me. I went to a top public university where 50% of the freshmen class think they're going to med school and then like 97% of them quit before o chem 2. Tons of weed out classes.
Anyway last year I was sitting on a pretty mediocre sGPA and low confidence in my ability to succeed in some of the pre reqs, namely the "physical" science classes. But I knew if I worked my butt off I could do well and I decided that this is what I wanted to do. So I kept taking the classes, retook and aced gen chem 1 and gen chem 2, aced o chem 2, aced biochem 1 and 2, physics 2, physio 2. I NEVER in a million years thought I could do well in O Chem 2... but I changed my attitude about these classes and my work ethic and ended up loving them once I gained a baseline of the material.
So, long story short, if you want it bad enough you can definitely do it. You have tons of time to dig yourself out. It's just a question of how bad you want it. If you think you could be as happy doing something else, then maybe now is a good time to walk away. If you're unsure about medicine, there's nothign wrong with putting the brakes on taking these courses, focusing on your major, and getting clinical experience through volunteerign or any entry level healthcare job.
Regardless of your choice, good luck man. You're gonna be fine! Just don't sell yourself short if this is what you want.
