Give yourself healing time.
Learning new, better behaviours takes time.
Schema Therapy takes practice, and lots of it.
Your schemas (belief system) were formed in childhood from your experience growing up and what was role modeled to you.
This is the basis for a persons behaviours today - both good and bad.
To learn new, better behaviours and do away with the old problematic ones is possible, and rewarding, but will take willingness, dedication and patience..
