need a lawyers advice on this

this must be my 10th time of requesting for a lawyers advice, beleive it or not all the advice i received previously was really helpful, although i don't know those who sent them but i beleive that God will favor you one way or the other, now to my case, months have passed after my devroce case, i succeeded in getting custody of my son, though with their malnupulation my ex- was given rights to see and take him away for two nights(weekends) i would have appealed to a higher court but felt the result will still be the same, now they are not giving up, they are trying all possible means to take him away, during the national day i traveled with my son, and it fell on the day she was supposed to have picked him. now when i came back the police came and i scolded them off, i have rights to spend the holiday with my kid, now they are pushing me to the wall, they intend to go again to the court starting i deprived them of the time to spend with my son. i know that i was in line by spending the holiday with my son, so i beleieve they are trying to get my son. i intend to move to another city, but i care about my daughter, if not i would leave, what do you suggest i do now, please kindly accept me,one last thing incase i do go to court again, can i represent my self. i am tired of hiring a lawyer and getting the same result, so this time i want to argue myself, what do you think. thanks for your advice...
