Being betrayed by a so called fellow Christian

It has been the most difficult two weeks of my life at work as well  as my health.  I suffer from these chronic dizzy spells which happen most of the time and every single day accompanied with migraines. On top of that my job is extremely high stress and there is an environment of hypocrisy now that is only making my illness worse! It has gotten to the point where I may take a short leave of absence and try to rest but at the same time find new work elsewhere.  If I don't my job will surely take me to an early grave!

Recently my co worker (who is actually a former Seventh Day Adventist but was still very spiritual) and I are no longer allies in this war called Management vs. Employees. I admit that with all the stress of my job as well as my illness plus taking meds on top of that has brought out rage in me which I unleash openly at the job. I wish I could video tape how these clients treat us and how spoiled and childish they can be. However up until now my co worker (who is the office manager) always seemed to have my back or would at least try to calm me down and we'd sit and talk about God, Jesus and Bible scriptures. It appeared that when I had started to take this road to Christianity it awoke her desire to do the same and therefore we fed off each others spiritual vibes.

During this transitional period of me tapping into my Christianity I find that things have gotten more difficult; sort of as if God is trying to test me or something. I haven't been too well as I mentioned above. I've flown into almost rage like stages at work from all the frustration and don't blame my co worker for being a little stand offish.  However it was nothing against her whatsoever but I guess she has started to take it as such.  On top of that I did notice that even before all this drama started she started to become sort of a brown noser with upper management as well as the new sales director (who is a female) in our office. With that came an attitude of selfishness, (which she's always been but brings it out more now) ungratefulness, (i have helped her with soooo many different things including her English), and two faced. I DEPLORE people like that and therefore I have distanced myself from her and her from me. She even treats my other co worker badly talking to her in any old which way, giving her attitude, making her do stupid little projects around the office and even going as far as not letting her leave early one day when her 8 month old son was sick with a high fever.  Meanwhile she is a Mom herself and has left work early in the past for him.

As much as I can't stand the sight of her I do pray for my co worker (the manager) and still remember the good Christian advice she has given me. However it hurts me a bit that things are so different now with her and she seems to do little negative things on purpose just to peeve us. She's all smiles and chatty in front of certain people but then talk up a storm behind their backs.

I admit that I am not perfect but at least I recognize my faults and admit to them. This person has gone far as saying that the only reason why she is with her son's father is because she is on his life insurance and if anything should happen to him she would get his money! (This was told to me by my other colleague who witnessed that particular conversation so who knows!) It is disappointing when someone who claims to be Christian is so full of negativity and darkness. I almost feel at fault for her becoming this way because of my recent anger. All I can do is keep fighting, praying for myself and for her.
