How low can you go?

I went through a fairly severe depression around a year ago, now I feel like Im heading there again.

Reasons to be miserable:

1. The company I work for was bought out, they havent as yet decided who or how many they are keeping. Uncertainty has never helped anyone, you like to have money coming in at a reasonable rate. How is a new company going to honestly decide if Im able to be a future employee if a) they dont really know what I do now, b) dont know what I want to do, and c) (more to the point) have no idea what Im capable of, as no one has my CV!! (HR dont have one, due to the way I was taken on board - apparently)

2. One rule for one, one rule for everyone else.. This has always made me frustrated and angry and miserable, and well pretty much any instance of it can bug me, but the bigger it is, the harder it hits me. More recently like back in May and June when I didnt get my new karate belt and finding out in the beginning of August it was because the guy in charge had believed something that was never true, and didnt think to ask, now means its circling round again, now, once more, a bunch of people who *did* get to do their belt in May/June are now looking at their next one, and Im not because he was holding me back because of this misunderstanding, now I have to wait at least 2 more months before I can get mine, although its quite clear Im certainly as good (if not better than at least 1) as they are.. So, bascially this means its all screwed from here on out, I will now always be at least 2 months behind. This is making me very miserable, to the point if I hadnt prepaid for a year, Id have quit in the last few weeks.

3. Its appraisal time, last years was never signed due to I feel a lie stuck right in the middle of it, I have no job spec to be compared against, and it will be done by someone who says they dont want me there..

So, Im sorry Ive been quiet, but this has been growing slowly inside and I guess it was time to share it.
