The increased anxiety is probably causing the lump in your throat. The meds are probably causing the increased anxiety. When starting most SSRI's there is a chance of increased anxiety. It may take a month or so to settle down. It usually decreases gradually until one day you realize it's gone! Good luck.
Thank you for your comment. I will give it another month and see how it goes. It does some to have the advantage of lifting the depression so lets hope this is at last the one and the anxiety calms down :-)
From my own experience, my increase in Wellbutrin from 150 to 300 caused a spike in my anxiety. I was very jittery every morning. It usually subsided a bit in the afternoon/evening. This continued for about 4 to 5 weeks at which time the medication had built up in my system to where it was working effectively. The jitteryness and increased anxiety went away. You need to give the medication a good 4 to 6 weeks to really see if it is working for you. You should see an improvement as you go along those 4 to 6 weeks.
