Hi MtnBikeChick,
I have experiences of citalopram and also work in mental health. When I had citalopram it didn't really make an awful lot of difference so was prescribed Sertraline which has been more helpful. However, it is very rare that SSRIs "heal" us as we have to work extremely hard to recover from depression.
In terms of the medication, SSRIs can take up to 6 weeks to experience the full benefits of them so if there is no difference after this time it may be worth going back to your GP to request a change of medication. Also, There are many different anti depressants out there and as individuals, we are affected by them differently. For example, I had a horrendous time on fluoxetine and the side effects were too horrific to wait for them to pass but you may take fluoxetine and find they make a big difference to you with no side effects.
In terms of other options, have you considered CBT? I deliver CBT for a living and can vouch for the effectiveness of it providing that people are willing to put 100% into it.
You can access it quite easily on the NHS but waiting times vary depending on your local provider and demand in the area.
Research has shown that the best results for recovery from depression in medication combined with therapy. CBT is very simple in theory and it is about gradually increasing your activity levels or monitoring and adjusting the type of activities you do. It also looks at unhelpful thinking styles and how to challenge negative thoughts. However, the treatment does require lots of hard work from the individual and commitment. It's a case of getting out of it what you put into it.
I'd recommend Coping with Depression book by Papageorgiou, Goring and Haslam.
The CCI website also has free self help materials for a variety of mental health problems which I often provide clients with: http://www.cci.health.wa.gov.au/
Http://www.get.gg also has some brilliant free resources.
