You have an RE code on your DD214 that will bar enlistment. If your condition has improved and you have recovered, you can petition
BCMR for correction, but I tend to think this will result in loss on military disability compensation and your PDRL status.
The answer to whether you can serve and its impact on your benefits would take some serious analysis. The risks are great for your benefits and I would advise you consider this closely and seek legal advice before trying to do this. This is not an easy question to answer, I do not feel comfortable stating an opinion on this without researching this more.
