I was somewhat in your position, I started off really strong and gave up my senior year which dropped my cGPA from 3.4 to a 2.95. I was burnt out from school, being an athlete, and having no idea what to do with a somewhat useless kinesiology degree. I took a few years off and decided to look at DPT programs but got a slap in the face with how competitive they are. I won't say that getting your DPT is impossible, but you would definitely need to bring your cGPA to as close to a 3.0 as you can. Since it sounds like you already have a lot of credits taken, taking courses to increase your GPA will take a long time and cost a lot of money. For reference, I already had taken ~130 credits and I calculated that bringing my 2.95 up to just a 3.2 would take 48 credits of all As (~2.5 to 3 semesters). I still only managed to bring it up to just over a 3.1. Then you must also consider your science & prereq GPAs. Depending on where that’s at will also affect your chances if you need to retake courses or not. Unfortunately you have to be realistic with your time, money, and academic abilities and it sounds like you might be burnt out on school. DPT programs are pretty reluctant about accepting someone who has shown that they have a hard time adjusting to learning a lot of material quickly or burning out midway through the program. It’s not personal, but it is an investment for them just as much as it is for you. This is my second cycle applying so I could get into a lot of detail of which programs to apply to and how to make your application more competitive, but the #1 priority will be bringing up your GPA. If you want more info you can DM me.
As for other career options, it really depends on what you type of job responsibilities you want and can handle. I don't know exactly how competitive admission to Physical Therapy Assistant programs are but that would be the next likely choice if PT is your passion. There are a lot of discussions out there between DPT vs PTA and many who are happy with their choice to become a PTA so I highly encourage you to look those up. There are even some transitional PTA to DPT programs if that’s truly your end goal. Other options could include becoming an Occupational Therapy Assistant, Medical Assistant (you'd have the ability to work in a specialty if you wanted like ortho, gastroenterology, family health, etc), CNA, nurse if you could start at an associate's program (still pretty competitive), EMT or paramedic, surgical tech, rad tech, pharmacy tech, lab tech (testing bloodwork and such), phlebotomist, etc. With all of these options you will need to complete more schooling/training even if it's only 6 months or up to 2.5 years. I would take the time to research and explore these fields before committing to a certain program. Outside of healthcare there are more wellness type jobs like personal training, physical education, and a wellness or activity coordinator for anything from small and large companies to nursing facilities. There is also the paperwork and business aspect of the medical field like working in medical records.
Lastly, I would solely focus on finishing out your last 2 undergrad quarters as strong as possible. It might feel like a drop in the bucket, but mentally it will help you feel like you've accomplished something and keep you motivated for your next steps in life.
