GREETINGS

i give a lot of importance to people who are not that important to me and who do not care for me or dont like me really and some people who not only care but are also negative like jealous of me or something like that.I give a lot of importance to them,so much they occupy my mind and thoughts a lot and that makes me give less importance to the people who really love and care for me and have taken pains for me and also this distracts me from my real purpose and mt real goals a lot.This attitude of mine hurts me a lot and causes a lot of pain ,regret and lack of concentration and this also hurts the people who are really important in my life.Sometimes i feel guilty for not giving importance to these not important people,i feel like i am doing something wrong ,i am thinking too much of myself,what will they think of me when really they dont care and dont want to care.Is there any way i can stop this,I have really tried a lot but still this happens.Please help me come out of this self destructive habit .Would be extremely grateful for any practical tips.Thank you for all your earlier answers.They were really helpful.But how do i be determined and disciplined enough to follow them.Sorry for my long question but i really need help.
