Help my anxiety keeps coming back

I’m not sure why my anxiety has not disappear, I have been taking my citalopram for 7 weeks and although I have very good days, other days I struggle waking up with all of these intros I’ve thoughts, what if I don’t get better? What if I will never get back to where I Was before? I feel my heart racing during the morning. As the day progresses I get better and there are other days where I feel perfectly fine like hey I am myself
Again no anxiety whatsoever ....the fear of not getting better or being sick makes me really anxious...my dr asked me if I felt better and I said yes because I am but still have bad days

Thank you Karen, I am a little better, but I will say not yet where I was before ...I just never thought that after years of not even taking meds and feeling great...there was this again ...anxious thoughts, anxious feelings ....
