One thing I can do at this point.

The field of awareness is this, there is going to be series of thoughts and emotions. Now the things you care about make you unstable, the thoughts will constantly change and they are mainly centered around past impressions, and desires.

There is insane amount of power if you like to exercise it. If I know what I would like to do in the middle of all this chaos I can choose. I can decide something and I can keep my attention next to it.

So you can actually create principles you live by, and slowly slowly you are changing the structure of the mind, against these consiciosuly chosen element of reality.

If the mind is nothing but the set of process then conscious choices has the highest weight.

You can choose these principle from the basis of facts and other peoples experience.
