I Have Been Prescribed Sedoxil 1mg On Split Doses Daily

I have been prescribed Sedoxil 1mg on split doses daily 1/2,1/2 and 1/2. Also prescribed Sertral 50 Mg for the first week then switch to 100 mg 1 daily. I also take Eltroxin 100 daily, metformin twice daily and steroids 5mg daily. (InFertility issues) . I have been feeling overwhelmed lately and have difficult sleeping due to anxiety and pulpitations , sometimes even chest pains due to stress at work . I'm worried about tolerance and dependency of these 2 new drugs I'm taking as I really don't want to become depend or not being fit to work or drive for work . I know most of my stress is work related. Hope these do not effect my tyriod disorder as well as this will increase my fertility issues. I have to go back to Doctor in 3 weeks time. Your honest opinion will be much appreciated . Thank you.
