Hi My Name Is Irma. I Am 59 Years Old,

Hi my name is Irma. I am 59 years old, hispanic with Neraupetic throughout my body. Nerve damage throughout my body. I have carpullel tunnel on both wrist (left & right). I am going to college on my 2nd year. I have pain from my neck, both shoulders, down to my elbow to my wrist and hand Then I have pain from the top of my shoulder (back) down my spine to my low back. Then pain on both legs from my hips to my knee down my legs to my ankle.
I am taking: for pain(NAPROXEN 500 Mg tablet; Lyrica 100mg capsule); my diabetes( Metformin 500 mg 2 x 3 per day; Metoprolol 50 mg; Januvia 100mg); and two for depression (ARMODAFINIL 250 MG Tab; BUPROPION HCL ER (XL) 150 MG
I have tiring to get Social Security Disability, but the judge states I am not 100% disabiable??
I am unable to stand for no more than 1o minutes without my back hurting; and unable to sit no more than 20 to 40 minutes before my back; hips and legs are hurting? So I am at the point I do not know what to do. If I should go back to work, and stay in school or just wait til social security makes a decision.
