P.S.- If it doesn't work out going off the prescription medication because of the surgery you've had, don't be discouraged, but work with your doctor to find the right medication for you and start out at a tiny dose if need be.
Think about how you felt so good when you were off the medication. If your pain level was okay, I would pursue with your doctor discontinuing the psych prescription medications (provided you don't have schizophrenia or something like that). I recommend you be sure and emphasize how much better you felt when you were off all the medication. You don't want to go off Zoloft cold turkey. When I went off it, I felt like I had the flu for a little while, but I'm glad I went off it. Tapering slowly off medication is something to discuss w/your doctor.
I would recommend if they still want you to take something for mood to tell them you want to try natural treatment.
When it comes to mood enhancing, if you would like some suggestions, please read the following:
If you are a Christian, God's Word, prayer, preaching the Gospel to yourself, and a Biblical counselor would be things you could pursue.
You could present an exercise plan (such as walking daily) which increases your endorphines and helps a person feel better.
Also, you could increase your intake of the good omega fatty acids- try freshwater fish, walnuts, almonds, macadamia nuts, pumpkin seeds, etc.. You might also take flaxseed oil or enteric coated fish oil capsules. And there is something that costs some money, but can be gotten over the counter that was recommended to me by a psychiatrist for mood. It is the Naturemade brand of Sam-E. He said studies had been done that showed it helped with depression.
Laughter works like a medicine, so I hope you can do a lot of that too- laughing with family and friends, watching a comedy, etc..
If possible, I recommend you avoid deliberately stressing yourself/putting yourself in the way of stressful situations where you will be likely to become anxious. Anxiety is bad for your spirit and your body.
Do things you enjoy and listen to music you like that lifts your spirits.
