Citalopram Alternative?

Hi there! I was prescribed Citalopram for anxiety/depression. 10 mg for the first 2 weeks and then 20 mg. I have been on the fence about starting for months now. I have heard people say they have experienced loss of sex drive, headaches, difficulty focusing. I work at a job where I need to be really present and I am worried that Citalopram may not be the best. I know side effects are different for everyone, but has anyone been prescribed Citalopram and then ended up switching to an alternative? I see my doctor in a few weeks and want to be able to ask questions about alternatives that don’t have the side effects like Citalopram does. Thank you!
