If there are "others" you most certainly have been abused as a child. "Others" are not created in adulthood. If there are "others", you will need to explore your childhood in great detail and be supported by a knowledgeable, experienced counselor.

How old are you? Have you had trouble with "missing time" and flashbacks, pictures in your head of experiences that are shocking to you but don't remember being involved? If so, you need to get the help. As you get older, you may find yourself having more and more difficulty and if there has been abuse, you may find yourself being flooded with flashbacks -- mentally and emotionally. You will need grounding techniques and skills. It would be well worth checking into all this.

All that being said, if you are having flashbacks, etc., this is not necessarily a bad thing. It is your mind telling you that it is ready to deal with the past that you were unable to face as a child. Children employ coping mechanisms as tools for survival. The mind of a child would be overwhelmed by some experiences and so will block them out so that they can get through the day/life. As you get into adulthood and are "maturing" emotionally, the mind lets glimpses of these things come to the surface so that they can be processed a little at a time.

Seek the counseling and find a way to afford it. There are counselors/psychiatrists who work on a sliding fee scale to make it more affordable.
