What causes Emotions: Colors

I am researching emotions and asked one of the social workers and Hinsdale Central to help me answer them. These are the questions I asked her:

1.  What do people diagnose as "emotions", such as depression for example. How can doctor's perscribe medicine for something emotional? Are emotions something that can be changed with medicine?

2. Does everybody feel and express the same emtoions?

3. What are different theories on emotions? (Broad topic- anything you would know)

4. Do colors really know how you are feeling, like mood rings?

5. Do colors affect how you are feeling (Theory: darker colors make you sad, lighter colors make you happy) 

My professional responded:

1. Medication is prescribed through tests, evaluations, and assesements. Medicine is described to someone depending on what is going on with the client. 

2. Everybody does have the opportunity to feel the same emotions as each other. Such as: sadness, happiness, and cheerfulness. Although, people do express their emotions differently.

3. My professional didn't really know a lot about mood rings but told me that depending on the person, colors and weather can take a toll on how someone feels.
