What effects do ADHD medicines have on depression and anxiety?

Answers

I used to take ADHD medicines and the effects are like a sad mood, irritability, and a flat affect or facial expressions, me personally didn’t like taking them because it makes me lose touch with reality, my mind is focused which is good, but i’m not social. i seem like i’m not in the mood for anything.. i seem sad when i’m on them. but later on in the day you know when they’re wearing off.
From personal experience, they make me feel less "numb" and I have become more emotional and able to function. Depression and anxiety is still there though.

Write a story in which an animal plays an important part.

Answers

Answer:

Hey buddy here is your answer:-

A kiara name girl was sitting in the attic of her house and teaching little students. A intelligent boy in the group was crying very loudly. When kiara heard the little boy's crying voice she asked him what happened cutie. The boy said that his mother was beating him with a long stick very tightly. Kiara left stunned and ask him why she was beating you. Because of not caring my pet dog she felt angry on me and beated me. Kiara explained him and everyone that animals are also same as human beings. Tina asked how?

Kiara said that when we are hungry we eat food, animals also eat food when they are hungry, we drink water they also do the same, when we are tired or want to take a sleep they also do the same. But there is a one difference. God has given us the power of speaking. But he hasn't given this opportunity to animals. So humans have become so greedy on this opportunity and think that animals are just silly fellows. But this is wrong. Animals don't sleep at night do you know why?. Because they take care of their masters house so that the human can sleep relaxed. They do very much for us but what we give to them. We don't give them food in correct time, don't take them for a ride, don't love them as much as they do for us. All the children were very much downhearted because they do the same with their pets. From the next morning they went for a walk with their pets, gave them food and water in the correct time,and love them very much.

So this story tells us that animals play a very important role in a human being's life.Hope you like it..............
