JTM --- Thank you for the update. I have often thought about you and your mom and was hoping that the two of you were getting counseling. Thus, I'm very pleased that the both of you are working on healing.
It's also good to hear that no one at school is giving you a hard time---instead your schoolmates and teachers have been very supportive. This, I'm sure, is making it easier for you to heal.
Whenever you feel "dirty", just remind yourself that none of this was your fault. You didn't ask for this abuse. In fact, you tried to resist and the perv had you thinking that he would hurt your mom if you told. Instead, you should hold your head high because you are very brave. Also, remind yourself that by speaking up, you are preventing this perv from hurting anyone else again. You have spared untold others from similar abuse.
I'm going to repeat what SoulfulSurvivor said to you:
May you find peace, comfort, and strength in the days, weeks, and months to come, and may you be a beacon of hope to other victims. God bless you.
Keep those words in mind as you heal. Perhaps someday, when you've healed, you may want to reach out to others who have been victimized as you were. You will be able to show them that you understand what they are going through plus you can show them that healing is possible.
May I ask this --- could you please keep us informed as to how things are going? I think we will all breathe a sigh of relief when the perv is convicted and locked up for years to come!
Do take care. All the best to you and your mom! Once again, thank you for the update.
