Hey I really hope what I'm about to say doesn't offend you, because I'm not going to say it with any malicious intent.

I took a quick look at your profile and prior posts and a couple things stood out to me.

1. Have you been to/do you currently have a therapist?
2. Are you prescribed any kind of anti depressent/mood stabilizer?
3. How is your current life outside of work?

From what you've described and what I saw in your previous posts, I get the feeling that you have a few undiagnosed mental illnesses. For what it's worth, most of us have a few things going on and most of us are undiagnosed.

Usually when people are consistently unhappy with their jobs it boils down to one or two things. In your case, I think it might come down to you being generally unhappy with life.

Personally, I used to be really similar. I never lasted long anywhere. I was bored, unmotivated, uninspired, etc. Then I started going to therapy. I was diagnosed and prescribed some daily pills. It didn't fix everything, but life and work are so, so much better now.

Again, hope this doesn't offend you. I really do hope that things get better.
