Am I scaring people around me?

You're not scaring people, they just can't deal with your emotional baggage. If I were friends with you, I would find it difficult to handle because I've never been in this situation before. I wouldn't know how to comfort or support you either :(

It's better to talk to people who understand with what you're going through. If you don't want to see a counselor (they scare me for some reason) I would go talk to people's families who are in the same ward or you can join an online forum dedicated to cancer-type issues

I don't think you are scaring them away. Its been my experience that people will tune out to what you are saying when you start talking about things that make people uncomfortable. Like dealing with your Mom who has cancer. Not that you shouldn't talk about it, but its just not going to work well as a topic for conversation. Being isolated doesn't help either. I'd suggest that next time you strike up a conversation keep all the stuff about your home life out of the conversation. It will be difficult to do, but try. Good luck. You are in a hard place.

Right now, you are going through so much stress you need someone to talk to to make sense of things and morn with. Everyone has different ways of dealing with tragedy. There is no other way you could communicate and no other way your family members could respond.

Sometimes you are angry and hurting inside, bringing about mixed signals that give people the impression you want to be alone and are easily bothered by people.

Find a crisis counselor to talk to, because I think you need someone to vent to who is willing to take it all in and not judge you.

Just be yourself and nothing more or less... and real friends or good company will come to you.. you can talk with others about their problems etc in order to help them and in order to see that you are really sensitive person even if you have some problems to express your feeling, dont be anxious, maybe this is just a difficult time for you, and thats all. you can also google it: how to express my felings, there r many online psychologist which can help you with that! good luck, everything is gonna be ok! :)

well if you talk about it al the time, people may get a little annoyed with the subject, so you may want to go to a therapists so they can help you, so you dont have to put that burden on your friends shoulders.
