feelings sentences

I'd like to know if I'm using theses adjectives in a good context:

scornful, tender, numb, lethargic and apprehensive

- This girl is so scornful, she always tries to us feel guilty of her problems.

Scornful is not correctly used here, being scornful is looking down on someone. Here are a couple of examples:

The girl gave us a scornful look because we could not speak the native language.

After hearing too many insults, the woman left her boyfriend when she realized how scornful he was. 

- English men are very tender... they leave let women pass through the door first.

Tenderness implies compassion or gentleness. For example you could describe a man’s "tender touch” or say “a woman smiled tenderly at her child.”  In your example of holding the door, “polite" or “respectful" would be a better word choice.
Tender is also often used for food that is cut into easily, when your knife slides into a good cut of meat you can say it is "tender". Another common usage is to describe pain, “my bruised foot feels tender when I stand up.”

- I felt numb when I found out my best friend is going out with my exboyfriend.

"Numb" is used perfectly here to describe a person who is in shock. 

- I woke up feeling lethargic today, I won't go to the gym.

Good use of the word "lethargic" as David previously mentioned, I would add the word "feeling" and move the word "today" either to the end of the sentence or before the comma. 

- My brother is apprenhensive for knowing his final school marks.

Apprehensive is used well here, though I would change the word "knowing". One suggestion is: "My brother is apprehensive in finding out his final school marks". 


Thank you very much for your help!!! Nice job with these, hope this helped =) 

Feelings sentences

I’d like to know if I’m using these adjectives in the proper context:

scornful, tender, numb, lethargic, and apprehensive.

-That girl is so scornful; she ridicules us about our problems. (To treat someone with scorn is to treat them with contempt or disrespect.)

That girl is so self-centered; she always tries to make us feel guilty about her problems.

-Englishmen are very tender; they bring flowers when their partners are upset. (Used in this way, tender is more personal and usually directed at a loved one.)

Englishmen are very polite; they let women pass through the door first.

-I felt numb when I found out my best friend is going out with my ex-boyfriend.

-I woke up feeling lethargic; I won’t go to the gym today. (You can do without the word "feeling" but it's more common in the US to use it in this context. You could also say "I woke up sluggish; I won't go to the gym today.")

-My brother is apprehensive about getting his final school marks. (You can also say "My brother is apprehensive about seeing his final school marks." "Knowing" is OK but wouldn't typically be used.)

 
Thank you very much for your help!!!
