My marriage fell apart at the same time that I started my business. I have been in a lot of therapy since for my own childhood trauma and its been painful and hard to concentrate on work. My startup has grown but I feel guilty about my lack of focus

Don't feel guilty. Just take it baby steps. It's hard to keep going when you've suffered a big loss, but if your startup is thriving it means you have something there! Turn it up 10 percent, then 20%, then 50%... Baby steps. Hang in there.

Imagine you bundle up the past in an airtight bag and visualize lugging to a deep river. Spit into the bag, tie it up and give it one good haul and send it drowning to the bottom of the river bed. Watch that image. Keep repeating that image in your mind. You will be surprised how relieved you begin to feel.

Therapy is great - well done on seeking it. A couple of things that are easier said than done - change your feelings and the emotions you associate with the not so great events in your life from negative to grateful. You wouldn't be where you are today without all those things happening, and where you are now is a budding entrepreneur. That's awesome. Fantastic. You've got courage and guts. Also, whenever to find yourself thinking or focussing on the past, remember these three words - control this minute. The past is the past and you can't change it. The future is beyond you and you have no idea what's going to happen. Control what you can. This minute. Good luck.

My prescription to you is to practice anapana meditation for 30 minutes a day. If you find that 30 minutes is too long, try 10 minutes and build from there.

I guarantee that within a month from the beginning of a dedicated meditation practice you will feel more focused and happier

Get drunk
Get sober
Get to work
That's how you get back to focus my dear.
