回复：请大家指点： 我在这公司还能混下去吗？

Cannot predict whether you can stay or should leave.
You are not alone in this - many people have in the similar situation.
1. Keeping in mind that not all deadline, e.g. deployment, can be meet. Lessons: if you know there is delay, make sure to inform all parties about it and make a point to tell every one YOU ARE DOING THE BEST YOU CAN.
2. Emotionally distant yourself from the situation - take a couple of days off or a vacation if possible. If none is possible, vente it out to a shrink. Things will look very diffeent afterwards. Bottom line; watch out for yourself, remind yourself that you are in this by yourself. Every one has their own agenda, it is NOT about you no matter what they do. Do not loss your faith - every one knows what is going on, no bosses, big boss, A and B boss. Keep a postive attitude and keep professional communication with every one.
3. Do not ask if "I can stay in this job", ask "have I done the best I can to protect myself". If the answer is yes, ask "what do I get from this bad situation" - income, experience or other etc. If you still have some thing to gain from it, stick on. If there is nothing for you, just hang on until you can leave for a better job.
Hope this helps.
