People just don't get it when they say " I totally get it " when they have not been through it. Why do we make friends through out our lives because in every mode of life we need some one to understand what it is like to be there. When you find a person that can actually know what you are going through you feel comfortable and happy to have them in the journey of your life. Some friends try to comfort you but often they might intrude into that corner where you have hidden your self to make yourself a better person in sometime. When the frequency doesn't match you will give up that friends and I think it's totally ok to let go coz this time is so valuable to you at this point to revive yourself  and avert the crisis than to feed their complexes. Friends don't pick on you. Picking on insecurities and brushing them off might make them feel intelligent or satisfy them that they did everything possible but  really that's to what friends do especially when you don't ask for help of any sort from that particular person.
