Am I crazy to even consider a 5-17 chapter at around 15 years and 5 months of active Federal service?

In October I want to see a PA about my achilles tendonitis and plantar fasciitis how it's worsening and to request a 5-17 chapter. The PA said that I must see podiatry, I mentioned to him that I have seen a podiatrist before. He still refer me to see podiatry. When I attended my appointment the podiatrist said that have a lot going on medically and if I've ever thought of an meb. I told her that I would take a 5-17 chapter so I can stop being an inconvenience and a nuisance to my unit and the Army. 2 days later I went to physical medicine and met with that doctor, after this cussing what's been going on in the last two months since last time I seen her. And how my back is worsening after NTC, because it was discovered that I have over a dozen bulging and diffused disc and a pinched nerve in my neck and my right arm goes numb. Also I have sleep apnea and I have to carry a battery pack to try to use it in a rocket launcher, which that was proven to be impossible because I have nowhere to recharge the battery pack.
So my question is should I just request a 5-17 chapter or go with the MEB?
That's also point out that the unit and the clinic will prolong it because of my current MOS.
