>looking back into my past for things I'd avoided thinking or talking about
For a long time I had many small and (apparently) inconsequential triggers which brought up past anxieties, or memories of the awkward and the nervous. Previously, I would remember such event and feel a brief stab of shame, etc. and then throw the memory back into the recesses of the mind to come back again whenever it felt like tormenting me. So a few a months ago I started catching these repressive thoughts - delibrately pulling them back after discarding them - and analysing them. I quickly realised that I had been letting them hassle me without giving them adequate thought as to why.
I think this is also relevant to some of the other comments about proactivity in challanging mental illnesses (not that I am qualified, or that it really covers anything or everything), in that the plunge into the icy and dark waters maybe harder to handle than the swim.
