<human>: To shorten what could be a much longer story, I had a few incidents and a lot of bad luck a few years ago that really set me back somewhat in life.  Prior to it, I was a really confident person and could articulate myself really well.  I was going places in life and I was doing well.

After everything happened to me a few years ago, I find that I'm almost just a polar opposite.  I feel like being in control of my life and being confident, I'm now just a lackey that virtually can't even find the courage to do anything on my own.  It hasn't helped that the jobs I've had in the past few years have put me in a completely subservient role as opposed to a managerial one that I'd had in the past.

I've found that it's reached me in so many areas.  I can't ever seem to stand up for myself at work, I cower down to anyone, I always feel like there's something I'm going to say or do that's wrong, I'm just feeling so meek and lowly.  I know it's affected my life otherwise, my wife has certainly noticed it.  Wheras before I was really sure of myself and confident, I can't stop myself from apologizing to her all the time and just cowering to her as well.  I know she hates it and I hate it too.  I just can't find the courage to act any differently.

I've been seeing a few therapists the past few years about this and some severe depression I've suffered as well, but neither talking it out or the forms of medication they've prescribed have really made any tangible change for me.

Can anyone recommend how I can get out of this?  I want to get back to being the confident and sure person I was before, not this coward I am now.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I took a hit in life that changed me from being a confident person to kind of being a cowering lackey and I could really use some advice on how to change that.
