Hi, I'd like to help you with your question.
It sounds like you have experienced significant trauma between your uncle and your parents abuse towards you. You may be experiencing post traumatic stress as well as depression.
First, if you feel suicidal at any time, please get to your local ER as soon as possible. It is important to get help immediately. You can get an evaluation and if needed, medication and treatment right away.
I agree with you, talking with a therapist is very important. You need the support as well as treatment for all of the trauma you experienced. A therapist can do a complete evaluation and determine what diagnosis you may have as well as offer appropriate treatment. You can ask your doctor for a referral, or if you attend church, your pastor could help you. You can also search on line at www.findatherapist.com. Your therapist can also refer you to a psychiatrist if you feel medications are necessary to help manage your symptoms.
There are also books that can help you get started with healing. One is called The Sexual Healing Journey: A Guide for Survivors of Sexual Abuse (Revised Edition) by Wendy Maltz. Another is The Wounded Heart: Hope for Adult Victims of Childhood Sexual Abuse by Dan B Allender Ph.D. and Dan B. Allender. Also, Adult Children of Abusive Parents: A Healing Program for Those Who Have Been Physically, Sexually, or Emotionally Abused by Steven Farmer is an excellent book for survivors.
Do you have anyone you can talk with? A trusted family member or a friend? Building support for yourself is very important. It gives you someone to talk to as well as someone to be there in case you feel bad. If you do not have anyone, try a support group for abuse survivors. It can be very therapeutic to have others you can talk to who understand what you have been through. Here is a site to help you find a support group- http://www.ascasupport.org/.
Try to take care of yourself the best you can. You deserve to feel at peace and sometimes as an abuse survivor, that is hard to find. Treat yourself well. Find things you enjoy and do them often. You may not feel like doing this at first, but if you take the first step, sometimes you find that the benefits are great and you can feel better.
I hope this helped you,
