Physics question about blood pressure and percent changes?

its sad indeed... and there is a little u can do at ur part... but u r facing this situation which means u can even carry it further... believe me ur peer group is just jealous of u.... u hav been at the top since so early and have so many duties to do... this proves that u r indeed an all-rounder with leadership qualities... which pisses others & drive them to jealous u.... really u shouldn't care about that but i can understand that... when others say about u.. u get real hurt and feel hollow from inside!! u mentioned above... but still try ignoring them otherwise all the damage will be to u!! this could be dangerous... i really, advice u of consulting some counselor... o good one preferably as this is just not gonna mess out school life and academic result but also can have impact on ur person life and mental stability!! i don't mean by making u scared but just advising u!!! reading this makes me conclude that u r dedicated to school activities.. in this situation peer group is likely to hate u, give u annoying titles and much more humiliation... but teachers... at least they should understand u.. if i'd have been u.. i'd have resigned...but u don't take any such action all at once... i again advice u to consult counselor decide what is more important to u.... school work... or people.. teachers.. academics... or whatever u cannot change in a trice... but many small steps will lead u to a change.. i consider u not to loose hope... don't feel alone.. at this situation u need friends... friends of almost same age group.. a person without friends is bird wiothout wings!! friend wish u lots of luck!! but do vonsult someone... it will prove healthy!
