Refraining from joining people who have unpleasant ways and behaviours

Q: I have a bit of a dilemma. I am a very sensitive and emotional person and I find it very hard to make friends. The friends I have are very loud spoken and speak to me with no respect and are rude to me, but i don't tell anyone because I don't want people thinking bad about them. But recently I feel so hurt with the way that they treat me I think bad thoughts, for example I wish bad upon them. I don't know how to stop thinking like that and I really want to stop! Example today they all ganged up on me because I told my mother that boys stay over at their house but I was not spreading rumors, I was just telling my mother because I was at their house at the time and they blame me for their parents stressing as we are studying away from home so basically I was labled as the bad one. Basically I just want to know how to react or handle their behavior and should I approach them and tell them how I feel? But they get very angry and it has to be their way so I really don't know what to do! I am also studying away from home and I do not like it and I am very unhappy. Please help me!

Being interested in a boy

Q: I am a 20 year old girl who is interested in this one boy and I really want to be with him but we can't because we have not made nikaah. His parents want us to make nikaah so it is halaal and we won't be commiting sin, but my parents don't want us to make nikkah as they think I am too young. My question is, am I allowed to make nikaah without my parents knowledge, rather than commit a sin and be in a haraam relationship? Please advise me on what I should do as my parents do not let me make my own decisions and I feel Islamically that I should make nikaah.
