Welcome to HCM!
From my clinical experince I can say that the symptoms of anxeity and fear are related to
depression. So, possibly your medicine is not working properly.
I think you should shift to some other antidepressant which can control
anxiety as well., like venalafaxine, or
prothiaden, etc. these are also equally good for migraines too. ( so, with them you can get benefit in both issues).
For acute migraines, you can take : rizatryptan or
sumatriptan , your doctor would know about them.
The memory problem is most possibly related to depression and anxiety, and hopefully will recover completely when you will get better. So, nothing needs to be done right now for them.
please see the doctor and discuss the above points.
Hope the reply is useful.
