Any success stories for Citalopram. Don't scare me please i'm on edge lately.

Hey; i suffer with health anxiety and it's extremely bad at the moment. I am female, 38, slim and healthy i dont drink or smoke and i go to the gym 3 times a week and walk daily. Yet every ache and pain i get lately (joys of approaching 38) make me think im dying. I can't shake this one off. I had tests recently for pulsatile tinnitus, im all good, appears to be a spine/posture issue but nothing sinister, however it's defo triggered my health anxiety to be at an all time high.

I went on Sertraline in October.... i went on it for bad PMS/stress/overwhelm and i had a panic attack 4 days in and haven't been the same since, so i am absolutely terrified of trying something else. I stopped the Sertraline. Having health anxiety means its not easy to just take medication and ride it out and chop and change because im terrified of the side effects.

Doctor gave me Citalopram. 10mg to have half for the start, so 5mg. It's still sat in my draw because im terrified. Feeling tired etc i can handle as it kicks in but i cannot risk my anxiety sky rocketing more, and then i dont even know if i go through that i'll even feel better at the end!?

I have stage 3 intense CBT starting on 30th January so i dont know whether to wait for that and see if i change my mind or just start it. Any advice welcome please. Thank you.
