Kaurp Pen jee,
It is better to be surrounded by positive people, which care for you at any cost.
Then it is also useful to be self confident and believe in oneself.
The world is negative by nature will try to put you down in one way or the other, but if you believe in yourself, then lesser the chances to be attaked and wounded. Sometimes, to defend oneself, though one is peace lover, give some punches(not necessarily physical punches) in return to the ill wishers, to show them, nobody can behave badly or come out with their nonsense and get away without getting something in return.
You see the world is like that, they do not like being decent or fair, they are just mad dogs, they just know how to bark ..... so just give them a good kick, to bring them back to senses.
i am not promoting violence, but just saying, enough, of putting the other cheek when getting slapped by the wicked for nothing, just because they think abusing others, is being like a fanatic stupid manipulator hero. So go for 2 eyes, for an eye .... or whatever you get hold first, break it on them, so they know and feel by themselves, their very own evilness.
You see, a thorn is removed by another thorn ...
So be strong and get justice to yourself, do not expect anything from others.
And then, never ever let frustrations enter yourself and get accumulated, because, once inside, they give birth to depression. Sometimes, due to circumstances, one can not do all this, in that case, do pranayam, and some yoga, to fill yourself with positive energy, and nullify and evil remanant within, thus regain confidence in oneself and start facing the world with redoubled strength.
And along with all this, pray Wahiguru to help and guide you with His Light, His wisdom ....
Sat Sree Akal.
