I think the first question you'll need to ask yourself is how much time and money are you realistically willing to spend to attain your goals? You're 25 now with a minimum of 1.5 years of undergraduate, with another 4 years after that, assuming you immediately get accepted. That means you will likely be ~31 years old by the time you leave school to enter the job market. The debt that you'll accrue during this time will be staggering, and that doesn't account for the money you've already spent at the other institutions you've attended. Plus, you will need to pay for the PCAT, studying materials, PharmCAS fees and secondary fees, all of which are costly in both time and money.
Next, you'll have to ask yourself why you were performing so badly in your courses. Was it a lack of interest in the subject, not enough time committed to studying, difficulty in the material? You need to be honest with yourself and identify why you weren't successful in the past so you can correct those issues moving forward. In all honesty, those F's in Gen Bio 1 and Gen Chem 1 are going to raise a red flag during the admissions process; a C+ in Anatomy 1 isn't very promising either. You will definitely have to retake Bio and Chem, and if I were in your situation I would not settle for anything less than an A. With that said, even if you retake these classes with an A, you will still need to explain to the admissions committee why you failed during your first attempt. You will have to be transparent about this, as there is a section in the PharmCAS application where you must disclose any situation where you were subject to academic probation, academic dismissal, etc.
I hate to sound discouraging, but the harsh reality is that there is an academic standard that schools abide by. Generally speaking, if you succeed in retaking those classes and bring your cumulative GPA above a 3.0, you have a chance at admissions. You will also need to do exceptionally well on the PCAT, get solid letters of recommendation from your professors/pharmacists, get some experience in the field (which you already have) and write a killer personal statement to be a competitive candidate. However, if you continue your current academic trend, you will not have shot, no matter how committed you are. Things are going to become much more difficult than the material presented in Bio 1 and Chem 1. If you are finding these classes too overwhelming, then I would strongly suggest you reevaluate pursuing pharmacy because the volume of information you will be responsible for will be much greater than it is now.
It is not the end of the world if you don't get into a PharmD program. If you sincerely love pharmacy, there is no shame in staying in your current position as a tech. However, if you want more, you will need to work an uphill battle for the next few years to prove you have what it takes to be successful in pharmacy school. It is a very serious commitment and should not be taken lightly. Your situation may seem bleak right now, but if you want it bad enough, you will need to do whatever it takes to succeed in your future coursework. Right now, I'd say you should concentrate your efforts on your classes and focus on completing a degree. That way, you will have something to show for your time in undergrad besides an enormous mound of debt.
Again, you have dug yourself a nice hole, but there is still the potential for you to redeem yourself. When you finish the next two years, you will be in a much better position to reevaluate whether you want to take things further. Best of luck, I hope this was helpful to you.
