Finding the most suitable medication/s for my depression/anxiety?

Hi… I’m 54 years old and have suffered depression since I was about 15-16 yrs old and used medication to treat the depression from the age of approximately 19 yrs old up until 53 yrs old… a little over 12 mths ago, for a number of reasons I decided to stop taking antidepressants. To cut a long story short I now find myself very depressed again, constantly tired, no motivation, very easily agitated and also quite anxious much of the time. I was taking 200mg Zoloft per day, which in retrospect helped a lot. I also suffer chronic pain which contributes significantly to how I respond to everyday life. I’m hoping to finding the most suitable medication or possibly a combination of medications to treat my symptoms.
