how do I remain unbothered by someone else bad energy? I live with an individual who I can not stand, every time she is in the house, her ?

You might consider making an effort to be nice to her. Since you have no choice being positive towards her may curb her negativity. You may be perceived as negative to her.

It takes two to fight.

Friend I know this isn't what you want to hear. But it's your perception of the other person that's bothering you. Change yourself you might not have money to go and move out but there's lots of free group therapies and church activities and counseling that you can go to if nothing more to eat dinner and drink something good with the group and escape the contact with the person that you perceive is causing the problem once you start doing these healthy activities you'll find that the problem no longer exists. And getting into contact with other people. it'll help you meet people that have money to get a job or maybe find a situation where you can get out of where you're at.

Try using your good energy to change her bad energy to good.

For example, offer to treat her to lunch.  Use the principles found below.

Rom 12:16  Live in harmony with one another. Do not be haughty, but associate with the lowly. Never be wise in your own sight. 

Rom 12:17  Repay no one evil for evil, but give thought to do what is honorable in the sight of all. 

Rom 12:18  If possible, so far as it depends on you, live peaceably with all. 

Rom 12:19  Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” 

Rom 12:20  To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” 

Rom 12:21  Do not be overcome by evil, but overcome evil with good. 

Good luck and God bless.

You just don't like your roommate. Either deal with it like an adult, or save enough to get a place of your own.
