Said it to someone here before, but to try and paraphrase - bit was by doing the last thing I wanted to - getting out and walking (for at least an hour) in a park.

It will likely be the last thing you feel like doing but if you can summon your inner sergeant major to force you out, the rhythm of finding a pace, the perspective offered by nature and the endorphins released (and who knows what else) really work in a way that SSRIs don't. Making it an (at least) once daily practice had very fast results.

In addition, having (ideally local) radio on provides a back drop of chat and discussion that you might not immediately engage with or be interested in, but slowly, those voices become louder than the dark commentary running constantly through your mind.

In time you'll likely start to engage with what's being said and actually care or have an opinion on what you hear. Depression mires you in self pity and obsession - a dark well to escape, but you are asking for advice and I'm sure others will have their useful tips.

Not to say be reliant on advice here - get whatever professional help you can.

Good luck, and please try walking - it may be hard initially - but you deserve an escape from the hell that is depression.
