Sorry to hear you're experiencing depression, Fuzzy.
Personally, I try to find distractions when I'm depressed. Even if those distractions only help for 5-10 minutes, that is 5-10 minutes where I'm *not* being consumed by depression. I think that's worth something. We all need to find a break somehow, so even 5-10 minutes is better than nothing.
One activity that could help you cope with depression is cooking or baking something you really like to eat. When you're cooking or baking, you're engaging all five senses: sight, touch, taste, smell, and hearing. IMO, the more senses that you engage at once, the easier it is for you to distract yourself. So, I think you should try activities that involve multiple senses, even if it's not all five senses. You can also combine senses: For example, I think I have a f***ing mouse in my apartment, so I have peppermint oil being diffused into the air (to ward them off... kinda like vampires with garlic

), but when I have the peppermint smell in the air and I'm doing something else, it really helps calm me down. (P.S. I recommend peppermint, vanilla, lavender, or honey for scents, although some people like cinnamon).
I'm not depressed, but I am stressed out and the peppermint relaxes me (which is a damn good thing because it works on the mice). It also makes it feel like Christmas... So I suppose if you really like Christmas, for example, you can get Christmas tree scents? I dunno. Just try to find a scent you like. A diffuser is only like $15-20 on Amazon, so... £12-16 in the UK. Then the essential oils are like $10-15 each unless you buy them in a pack (but usually sellers on Amazon like to include some scents that smell like dogshit because no one buys them and they can't get rid of them... so you're kinda "overpaying" by purchasing oils in a pack because you're buying something you won't use). I get the 4oz bottles. They come with an eyedropper and you only put like 3-5 drops of the oil into the diffuser, so 4oz will last you a LONG time.
