Hello from JustAnswer.
I am sorry that you have been going through this difficult situation.
In this situation, the usual assessment would be a psychological assessment. Actually, either assessment would be fine, but the primary advantage of a psychiatric assessment is when there is such problems that it is likely to need medicines. From your description of the situation, there is a good chance that the assessment may only be a reassurance that no mental illness is present, other than the stress in response to the situation.
If I can provide any additional information, please let me know.
