Hello P25, and welcome to Anxiety Zone...
Wellbutrin (Bupropion) is a non-tricyclic, atypical anti-depressant used primarily to treat depression and aid in smoking cessation. It is considered to be one of the most "stimulating" of the anti-depressants. I can be used to treat anxiety disorders, but because of its stimulating nature, it can make anxiety worse in some individuals.
I was started on Wellbutrin when I was first diagnosed with GAD and panic attacks. For me it made a bad situation worse. My current psychiatrist told me that she uses Wellbutrin for her patients that are so depressed that they can't get off the coach, and doesn't really use it to treat anxiety disorders.
As with all anti-depressants though, keep in mind that what works for you, might not work for me, and vice-versa.
I was started on Celexa some 4-5 months ago, and am doing quite well on it. Celexa (Citalopram) is considered one of the more "calming" anti-depressants. I am not certain how long you were on Celexa, P25, but it is actually the norm to see an increase in anxiety when starting a selective serotonin reuptake inhibitor (SSRI). This is a side effect of these anti-depressants. My anxiety went through the roof when I started Celexa, but after several weeks, the anxiety returned to baseline. I would now say that I am 90% improved over the way I felt some 4-5 months ago.
Anti-depressants are worth their weight in gold, but there are other things you can do to also help with anxiety disorders. Thes include therapy, exercise, and the use of omega 3/fish oil.
The very best to you, P25!... Chuck
