Your employer may have an Employee Assistance Program, and this can be a good place to get referrals. In most such programs, the counselors can only see people for a very limited period of time, so they are very experienced at providing referrals. Just tell the counselor you're there to get some referrals. If you're going to college, try checking with your school's counseling center or student services office. The people there often know a lot about what's out in the community to help their students with particular problems.
Bookstores often have recovery-oriented community information.
If you attend support group meetings in your community, ask the other group members for referrals. This is one of the best places to get referrals because the people doing the referring have actually been clients of what they're reffering you to. Support group members know who the good therapists, etc. in town are, and which you should stay away from. If you're looking for a support group, try checking the newspaper. If you don't subscribe to the paper, look at the papers in the public library.
