I have been on citalopram 15 years need to change

Has anybody had to change from citalopram to fluoxatine? I need to change as citalopram doesn't work anymore. I have dipped back to deep depression. Dark thoughts emotional, don't want to do anything, angry, moody . My husband is great and my son's . But I'm scared of the withdrawal. Has anyone else experienced this change?

Hulo Jennifer! i am back on citalopram, i have on and off taken it for yeaaarrrs also and it just does not do the trick! have u got a good doc? i lived in the uk for 30 years and the med help is non existent, they kept on giving citalopram even when it is not good for epilepsy and i have it.. i have started again on 20mg 3 weeks ago, today i want to kill myself! ah ah ah  i send a big hug xxx

I have different doctors say different things. I'm asking to be referred back to my phyiciatrist. I can't cope with it either. So gooyto have some one understand. Sending hugs
