Hi MG and welcome!
I think what you are experiencing is a double whammy here...
You are weaning off a benzo...and starting an SSRI.
I think you can expect some feelings of discomfort unfortunately...and you are just going to need to give it time.
SSRI's will often cause and increase (ironically) of anxiety upon starting. These feelings will phase out after the first few weeks...and you will likely end up with a good med for yourself.
Keep following your doctor's advice for your wean. You will not have seizure issues if you continue to step your dose down slowly and consistently...so don't worry about
that.
For help in all that your body and mind are going through now...here are some great stress relieving exercises. Practice them everyday, and they will help.
