"If playing with girls toys is discouraged, tendency to draw or doodle feminine things or "pretty ladies" which are identified with (for biological males with similar but reversed for girls)"
this was what I did with my time as a young teen.
"Poor educational performance, below what one might expect of them."
yep that happend to me too
"Obsessive with Hobbies/pastimes - when doing things they really enjoy they can sometimes over-immerse themselves in them as displacement activities (saves them from having to think of their problems)."
yeah I used to live in what my psyche would call "My Fantasy World"
"Depression, sleeping late during the day and unable to get off to sleep at night, constant cravings for Carbohydrate-loaded foods (Starch, Sugar and Cellulose)."
I used to eat so much I ended up with alot of weight for along time.
"Often on the receiving end of bullying, sometimes severe"
this has happend to me all the time even on the weekends from school.
"Few friends, and a lack of a normal social lifestyle for a teenager.
Spending long periods alone - e.g. in the bedroom, or going for long aimless walks alone."
I only had 1 friend and I did used to go walking alone to get away from society and I did spend time in my room alot playing games and secretly crossdressing in that time.
"Appearing more friendly with the 'opposite sex' as their main group (i.e. boys who are more friendly with girls, and vice versa)."
yes and no depending on how friendly the girls are but most of them just saw me as a friend they can chat to but I did feel more comfortable with girls than guys in a group.
that's all I can say about the link.
