Years ago I was in a similar situation. I was fired from my first 2 jobs out of college. My first job lasted 8 months and my next one lasted 1.5 years. The official reasons given to me were similar to yours, but those were just "bland" reasons they give to anyone they want to fire. My real problems were personal, and even if HR knew about them they wouldn't comment on them for fear of discrimination. My real problems were:
- Severe untreated ulcerative colitis
- Depression
- Sleep Apnea
Given these personal problems, it was literally impossible for me to be a successful employee, these things HAD to be fixed first before anything else.
If you have severe untreated ulcerative colitis or chon'sChon's disease your life is going to be a wreck. I literally showed up late to work because I was in the bathroom too long and my insides hurt so bad, or later. One time my boss asked me why I was taking so many bathroom breaks (an EXTREMELY unprofessional question) and I literally did NOTnot want to tell him. Not to mention your sleep will be rather horrible because you are in so much pain.
I think a lot of my depression was due to my physical condition. I didn't feel well, and that made me extremely unhappy, and unwilling to make friends or even leave the house for long periods of time. I was in an extremely bad place mentally, and even after I was treated physically, I needed to see a psychologist for years after before I felt my depression start to lift.
Sleep Anpena sucks too. I would get 9 hours of sleep every night and still feel groggy in the morning. I'm pretty sure my managers thought I was out partying every night, or a severe alcoholic rather than someone who just didn't sleep well. If you have this problem, see a doctor and he will refer you to a specialist as it's an easily treatable problem.
Eventually I had these problems treated and I was much happier. For a few years I had to work some less desirable jobs but I was eventually able to recover and get a job in my field that I was happy with.
I realize my above experience is anecdotal and there is a good chance none of these are your specific problems. That being said, you need to take a good hard look at your personal problems and see if they are holding you back. I was in denial about my problems for many years. In the end the only thing I'm sorry about is that I took so long to address them.
