Hello Candy, and a warm welcome to the forums.
It's sad to know you are alone, unfortunately, when we think in a negative way due to the situation we are in, then to become positive is to limit the amount of negativity that we are experiencing by trying to have more positivity in our life, that's easier said than done.
Sometimes it might be better to change the situation we are in, again, easier said, but it would be great to hear back from you, and perhaps tell us the position you are having trouble with.
Take care.
Geoff.
