First off you should be so proud that your child feels comfortable enough to come to you when she feels that she needs help. Some children can never do this and often their problems go unnoticed for years. If she says she has had thoughts of hurting herself then she definitely needs therapy and I am glad that you are looking for someone for her to speak to, don't be shocked though if the first therapist does not work out. It often takes several tries to find the right therapist or personality match, like the right person where your child feels comfortable talking with so it may take some time.

The most important thing you can do is keep the communication open and do not be judgmental, let her talk to you and be open with out fear. That is when teens start hiding things, when they get afraid. Have you noticed any depression, anxiety, serious change in behavior or eating habits? Have you looked in to art therapy? it can be helpful for some people.
