Hey!

Just wanted to ask. Is it normal to completely forget something bad happened, as soon as you stop feeling bad? I just go to feeling nothing (the usual) and its like the bad thing never happened. F.e. situations with friends or family which caused me feel extremely bad.
I had it happen a few times now that I told friends of a problem that worried me, and they told me the same thing already happen thrice in the past, or being stunned how I can go from hating someone for sth they did and being immensely hurt, to forgetting they did it as soon as I'm normal again (1-3 days?) and praising them for being the best person ever. I cant remember, or just barely. 
This is causing these situations to repeat over and over and for me it always feels like its the first time that happened. I cant solve shit like this! And I cant trust my memory at all.

My therapist told me there's no problem, since it's a  good thing if I'm able to forget bad things! But can that really be true? He said I'm making up problems, since thats a great thing! 

Is he really right? :')))
