1. You're not weak and spineless. It takes giant balls (excuse the phrase) to post personal experiences and feelings.
2. Being bullied can be a devastating experience. You had and have the right to feel hurt and even traumatized by it.
3. From what little I know of you, you appear to be empathetic, compassionate, and strong.

Please don't berate yourself because, well, your view of you is just plain wrong.
