Hi Marchmars. Welcome to Psych Central. Sounds like you are in a highly stressful situation with school and competitive and bossy relatives, that sounds like has even got to be mentally and emotionally traumatic. There are ways to cope with these kinds of stress, like self care

Of course I would highly recommend a therapist, but if that is not be possible I would like to recommend a resource here at Psych Central that you can send in a question, and get a reply from the therapist as their time allows. Here is the link for that.
Ask the Therapist

Many people who are actively involved in Psych Central find it helps take them out of their own problems to develop empathy for others. And their problems though still there are more manageable.

There are lots of compassionate people here that can make the load lighter by sharing and caring. Feel free to participate actively at Psych Central. Some people find the forums give them the compassion and empathy they seek. http://forums.psychcentral.com
