There are two known types of atelectasis. The first type is called acute atelectasis which usually results from surgery involving the opening of the chest cavity or the abdominal area. This type of atelectasis may also result from physical trauma to the lungs like during car accidents or stabbing incidents.

You say you are still depressed even on meds. They do take about 3 to 4 weeks to work but if you have been on it for a good while and it is not helping then let your doctor know so he can try you with something else. I wish you all the best and write again as you will find support here.
