Does anyone know how i can get over the fear of rejection ?

please believe me,when i say,that i was in your shoes for many years,ive been through alot of therapy,and im also bpd,and depressed,you dont have to answer me, just remember this,you need to love yourself,as a worthwhile unique person that you are,because no amount of therapy,or meds will take away low self-esteem, my prayers are with you, a friend
