ABSTRACT:- COVID-19 Lockdown causes different students and people affected by depression and anxiety and
health problems in the society of Ethiopia. Among these commit suicide in the pandemic [3]
problems mental health problem such as anxiety,
depression, panic and fear are common. This research Depression is a disorder that affects how you feel,
aimed to redesign a neural network model of an anxiety behave and the way how you think. Depression is a bad

Anxiety Depression
I feel tense or 'wound up'? I still enjoy the things I used to enjoy?
I get a sort of frightened feeling as if something awful is about I can laugh and see the funny side of things?

Worrying thoughts go through my mind? I feel as if I am slowed down?
I can sit at ease and feel relaxed? I have lost interest in my appearance?
I get a sort of frightened feeling like 'butterflies' in the I look forward with enjoyment to things?

I feel restless as I have to be on the move? I can enjoy a good book or radio or TV program?
I get sudden feelings of panic?
The expected answer and score point for each question in the questioner for Anxiety and depression is shown below in Table
1[18].
The collected data for Anxiety and depression score level of individual was categorized as normal, mild, severe and
moderate using HADS technique [18]. The four categories such as normal, mild, severe and moderate are coded using decimal
numbers as 1, 2, 3 and 4 respectively and these used for training in the neural network. In Figure 1 the questioner collected from
each person is coded from p1-Ans to p1607-Ans and the questions are coded horizontally with their respective answer score
vertically.

The accuracy result of the model is compared with the manually calculated value by hospital anxiety and depression score.
The anxiety and depression error rate measured in absolute percentage value (APV) of 0.017379846 and 0.018365 respectively.
Moreover the sensitivity is calculated for anxiety and depression using APV as 0.926666667 and 0.945205479 respectively, the
specificity of the anxiety and depression is 0.997940975 and 0.996577687 respectively.
