Levels are super high, not sure what could have changed??

Hi all, new here! I've had hypothyroidism since birth (thyroid never developed), 39/f today. I've been on 125mcg of Levothyroxine for about 2 years now and the past couple of months I've just felt OFF. Extremely tired and lethargic, just not good. I went in for my annual physical yesterday and I got my results this morning to show my T4 was in normal range but my TSH was at 12.39!!! The biggest change in my life the past few months have been an addition of sertraline (50mg Zoloft) for anxiety and 40mg omeprazole for GERD/severe acid reflux. My doctor and I figured out a good schedule to take each of these so they would not affect the absorption of each other but I can't help but think one or both of these could be affecting my levels. Is anyone on either of these medications with Levothyroxine? I am still waiting to hear from my doctor to see what she recommends but would definitely appreciate some insight from others!
