You may have heard of the saying 'life is not a bed of roses'. Certainly, it is not. Getting sad at one point or the other is a common thing for people but there are ways to solve this by cheering them up. After all, there is no better remedy than a smile or a laugh.
Things to say when cheering someone up:
The first thing you would want to do is take out some time in listening to them first. Find out the reason behind their depression and think about it. Note that you should not interrupt them while they confide in you. Afterwards, comfort them and give them an honest piece of advice. A typical example is 'everybody fails in one subject or the other. Nobody is perfect. Think of it this way. You have the opportunity to do better by retaking the course in the summer vacations. There is always room for improvement but you will need to work with all your heart this time'. This is a good way of conveying your message as you are adding a positive tone to it while implying a small warning at the same time. It is better than saying 'repeating a course is one of the biggest drags ever. You should have paid more attention to studies rather than messing around. It is too bad. You have wasted your time'. This response will make the already depressed person feel more shattered.
People who are down in the dumps would like to hear a good word or two especially from a friend. Remember, there are some sentences which you should always use, preferably near the end of the conversation, like 'everything will be alright'. The key is to imagine yourself in their situation before answering them.
More responses include 'there is no reason to worry about anything', 'whatever happened is for your betterment so just leave the past behind because the future looks promising'.
Relate to some good quotes. For example, 'life is far too important to be taken seriously'. In this way, you are telling them that a person becomes unhappy when things are taken too seriously. So the goal is to divert our attention away from the seriousness and take things more lightly. When assuring a friend that you are always there for them, say 'the road to a friend's house is never long'. To brighten up their mood, include 'one day, we are going to look back at this and laugh'. The purpose of this is to soften up the situation even if things do seem critical.
Tell them that they look beautiful when smiling. Tell them that it may be cloudy now but it cannot rain forever. Assure them that their depression is temporary and there is always a silver lining behind every cloud. Depression is a normal but undesirable feeling in life. We should be here to reduce the suffering of others by cheering them up and these simple words can really make a difference when conveyed properly.
