my opinion....everything you posted can be normal for some people..

example I know a few people who have never been sexually abused and have gone through what you have. their problem nothing...its is just normal for some kids to prefer shirts, and jeans\pants over wearing dresses. it would be different if say we lived in the 1800's when girls and women had to wear dresses and skirts. but children have been wearing shirts and pants for hundreds of years just based on the fact that for some it makes them feel more comfortable. feeling naked\exposed and such in a dress\skirt is just one of those common place things even adults feel sometimes when they wear dresses\skirts. I have a co worker who wears dresses\skirts at work but the moment she gets home they are discarded for what she called comfort clothes (jeans, shirt, slippers and a soft blanket thrown over her shoulders. a cup of coffee in hand and the remote for some time in front of the tv)

my point please dont self diagnose youself as being sexually abused based on your clothing choices and bedwear.

sexual abuse as a child comes with all kinds of physical documentation. for example contact your medical doctor, they will be able to tell you whether you presented with internal bruising, internal tearing, sexual abuse of a child leaves a special kind of bruise marks that can not be explained away as falling down. your medical doctor will be able to tell you if there was any of the key documentations that have been in place for over 30 years that a doctor in NY as a mandated reporter must look at and report when doing their basic school physicals for sports and such.

teachers in NY state are also mandated reporters and have been for over 30 years so they too would have documentation of anything that the state tells them they have to be on the look out for in working with children in the state of NY. you being 18 you can go to your schools and fill out the paperwork and read your school file on you. if you were an abused child or any thing questionable like unconsciously touching where it itches and bothers a child is common for sexually abused children, just like if a child feels an itch bruise or scrape on their arm they unconsciously rub, touch,itch that arm.) my point your school will have documented proof of abuse of any kind in NY state.

there are all kinds of ways to find out whether you were sexually abused as a child in NY. good luck in your search.

as for healing if it turns out you have been sexually abused yes healing is possible with out remembering. here in NY state treatment providers treat symptoms. so what ever problems you are having is what treatment will focus on. now days remembering is not a requirement.
