I could write pages on this but 2 keep it short 1) if you are depressed, _do_ exercise - there is lots of research backing that up - search for examples of duration etc. and 2) it seems for the OP a ma wouldn't necessary be better than many other activities but since she's interested in Judo, go for it! .. a key I've realized is being proud of somethng _anything_ - remember the brain sucks at keeping attention on multiple things at the same time. Be proud about your nose picking abilities, be proud about your ability 2 evade doggy doo on the sidewalk, be pround about being able to produce a nice sound when you step in said doo.
