It is often heard from many, "I'm all alone ; people who stood with had left me, I don't have good friendships..."etc. The sad part is, many such people has broke down with these problems.
It was a grief which mentally exhausted me too once. Thus, recovering from the isolation from your closer ones is not an easy task and I'm pretty sure about it.
Later, I realised the fact that grieving all the time for this is of no use. Then onwards, I started discovering myself and I can say that I've succeeded in it to some extent. Today, I have many people to love and to be loved ; but I am confident that it won't break me down, even if they leave me alone, otherthan a small worry.
We should be able to get over the people who left us alone. Just think that they don't deserve our friendship. Grieving always leads to mental stress and may even make you think that life is all over!
It is our life and it is just our necessity to find our own happiness. Let us not pledge our peace and happiness for/in anyone. If we do so, the withdrawal of that particular person from your life may disappear all the happiness in your life.
You should find the way to 'get out' from a person when you are about to 'get inside' them. Else, it may lead you to depression, if they leave you. Do not rely on anyone too much. Do not believe anyone blindly.
To everyone who are facing isolations and exclusions from others ; Dear all.... Just igore them all and think that they don't deserve your love, respect and friendship. It is your life and it is your privilege to be happy. Don't let anyone spoil it.
Wishing you all to have a good day.
Thanking You :)
