Though most of your life may be affected by your perception, those things become true for you. And they appear more true when someone (even yourself) confirms it, whether distorted or not. Still there will always be someone more confident than you, and someone who dislikes you, and someone who makes you feel insecure and awkward, and someone who makes you feel like you don't belong. But there are more to life than just "what ifs" and perceptions.
An absolute truth that might be weighing down on you for example could be the bills you don't have enough money to pay, or that your grandmother is in a hospital and you realize last time you saw her, all those years ago, was the last time ever. Or your own health might be failing at an alarming rate, or maybe that as time progresses, your goals will be less and less obtainable. Thoughts like that also go on constant repeat, eating you from the inside. How would you discredit that? And how would you be so sure that you can allow yourself to discredit the other thoughts?
Note that I say "you" as in an individual in this segment above. It could be me, could be you, could be that guy or this chick. It's just general.
Don't you tell me what I've tried and haven tried. Do you think it's easy to sleep when your mind is constantly screaming at you? Of course I've tried. I can't just discredit everything.
We dont know whats best for us, that is just a belief\opinion, we have no idea whats best for us since every bad things has good things coming from it, and every good things has bad things.
Soo, since we dont know whats best for us, every outcome is fine , even death.
About goals, we dont need goals to be happy, in fact they cause us anxiety just thinking about failling it (if you still believe that it means something, which it doesnt.)
What have you tried, have you tried seeing the positives in bad things? Have you realized that we dont need achieve anything to be happy?
HAve you tried seeing the full spectrum instead of just believing what your mind says?
