I heard all foster children have some type of health or psychological needs and are difficult to care for, is that true?
Children in foster care have experienced trauma. Children are not the problem. If anything, the environment they were rescued from, is the problem. In short, the answer is, no. Keep in mind that in all cases, the agency will work with you to assist you in providing the optimal care for children. Do not let the concern about children behavior keep you from your calling.
