My body is addicted to many prescription drugs. My pain started about 4 years ago after I had a nervous breakdown and tried really hard to overdose. I obviously have a high tolerance for medications of any kind. Since then, I have chronic everything it seems. Depression, anxiety, chronic fatigue, PTSD, fibro, arthritis of an elderly person and I'm only 37. If "itis" is at the end of the word, I have it. Tendonitis and bursitis in both knees and shoulders.
