so say the x axis in the attachment was 'different diagnoses' and each bar represented a specific disease and the y axis was mean serotonin levels then the larger the error bars then the greater the standard deviation about the mean of the bar the error bars attached to i.e. for that specific disease. Is this correct?

The error bars are presumably the 95% confidence interval for the data. In normally distributed data, the 95% confidence interval is directly related to standard deviation and inversely related to population size.
This data is likely not normally distributed. It almost certainly is skewed right. Standard deviation might not be the most appropriate measure of population distribution since the standard deviation assumes the data to be parametric.
I only took one statistics class in undergrad, so that is about the sum total of my knowledge
