i take a different SSRI called Paroxetine (Paxil).
i can't really say if it's totally different from citalopram or not. for me meds have helped hugely. i do take another drug along with paxil though, since my anxiety is through the roof.
maybe this site can help you learn more about it.
citalopram (Celexa) - drug class, medical uses, medication side effects, and drug interactions by MedicineNet.com
one thing though that you have to consider is whether taking a med will help you more than if you're not taking it, and of course the possible sides effects.
for me, i was in really bad shape, so i had no choice, and i have to say i haven't regretted taking meds. ask your doc what is his/her plan with giving you the meds, and whether this will include increasing the dosage or not, or if you can try them out for a few months and if it's easy to get off them if you see they're not really working.
