My mom isn't doing so well.. Im military so im not always around.. she has been told she has Lyme and/or MS, but no doctor has given her a clear answer..

Some background: My mom was never suppose to have kids, but she had me and it almost killed her, she recovered and im still here.. She was a single parent for the first 14 years of my life.. She has always been stronger then me (and I was 3rd place in weightlifting out of 6 schools) and has always been able to beat me.. she taught me everything, we built the house she's currently in and the 3 before it.. I never expected her to go from kicking butt and building houses to not being able to drive, quit her job, and has no strength or energy..

She was always there for me and I feel like I left her when she needed me and now when she still does.. I don't know what to do, she's the only one in my life to ever give a care about me and hasn't left me or lost hope.. I could separate from the military on good terms to take care of her, but I have bills and don't have any money saved up, but I feel like if I stay in the military im letting her down.. I don't know what to do, its killing me.. the other day she cried in my arms (first time ever) and I lost it, I went in my car and cried.. Feeling lost and confused..
