Start to exercise! Literally, destroy yourself physically, it could help. ;-) I think you can't fix your mental problem only with mental toolkit. It's important to keep your balance of mind and also body. I'm not an expert, but it works for me.
Well, this is phantasmagory. The mars has actually very low magnetic shield and almost no atmosphere. The core of mars, which should generate this kind of field, as earth do, is burned out. There is no way how to create and sustain a sufficient atmosphere to colonize this planet. What worse the earth come to this point soon or later and solar wind flush all atmosphere and vegetation and there will be another mars on solar orbit. Humankind should focus to leave this world and transcend to another form of life :))))
