I have jowls and I feel like my face is falling. Thoughts and opinions please? What should I do? (Photo)

A short scar facelift is a great option for many people. The recovery & downtime is very minimal. There are usually no drains, most people can go out the same day, you can shower the next day, there're no scars behind the ears and you can wear your hair up anytime and most patients take no pain medicine. The result is usually the same in selected patients as a full scar facelift but it really depends on your exam.
Surgery is not for everyone. In today's day and age, there are many nonsurgical options to consider although surgery usually gets the most improvement specifically of the neck and jowls.
I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of mini facelifts and neck lifts but also offers all the nonsurgical options such as injectables and laser treatments. Go over your concerns with them and make sure above all, you walk out of there with several options and an idea of the pros and cons to each of them as well as realistic expectations. 
I hope this helps and wish you all the best in your surgery and event. If it does, please take a moment to up vote this answer on the “respond” button on the top right.  

If you feel that your face does not reflect how young you feel inside, you may be a candidate for a facelift.During your #consultation, your skin texture and elasticity, as well as your underlying skin structure and your facial bone structure will be evaluated. Based on this evaluation, your board certified plastic surgeons will create a custom surgical plan, detailing specific techniques and recommendations to meet your goals. In doing so, he or she should be sure to have a full understanding of what results you expect.If you are not a #candidate, your surgeon can make other suggestions to address your concerns and objectives.Patients who desire facial rejuvenation that is affordable, quick, and effective should consider the Lite-lift™. Like the Life-Style™ facelift, this is a modified facelift that can be performed in the office with a local anesthetic and improve signs of aging around the neck, jawbone and lower face. These procedures are not "Thread-lifts" or "String-lifts". We do not use the "barbed" sutures employed in these other lifting operations. The Lite-lift™ uses longer lasting techniques that are discussed below. Because the incisions are limited, there is less bruising, swelling and healing time for most patients. Many patients can be back to work in one to two weeks looking rested and more youthful.The best candidates for #LiteLift are patients 35-60 years old with early changes of the lower face and the neck. Older patients who cannot or do not wish to have a longer operation or general anesthetic can be improved with a Lite Lift™.Lite Lift™ surgery is individualized for each patient. The best candidates for Lite Lift™ surgery have a face and neck line beginning to sag, but whose skin has elasticity and whose bone structure is well defined and do not smoke.

If your objective is to do all you can, a lift would help you. If you want to do something to help the situation but not entirely address the situation, then fillers might be a consideration.
