Hey Reddit,
This Sub has helped me out over the years. So I wanted to share the techniques I have found help me, with the hope some of you might find something new to try to help you with the day to day...

Exercise:
Might sounds obvious, but I never realised how good some serious cardio was for burning off all the adrenaline. At the start I was just doing 1-2km and have built up. But even when it was relatively short distances I found that I felt much better after. I also found playing around with what I was listening to helped. Music, actually made it worse. I got frustrated with the changes in tempo and that I was running out of time with the song. But when I switched to a podcast or audio book it worked really well. 

Gratitude:
This might sound super hippy. But it really worked for me, and I only discovered it relatively recently. Before I go to sleep I list eventing I am grateful for that day. Sometimes the list is long, sometimes its short and as simple as "my bed, getting through today and having something to eat." It's almost like the the polar opposite of anxious thoughts and I found that over time, when I have an anxious thought a grateful one automatically comes straight away to neutralise it. 

Yoga:
This one changed my life. As crazy as it sounds trying to move in time with breathing instantly clears the mind. There have been many times when I have gone in to a class feeling super anxious. Then come out feeling at peace. If you haven't done yoga, forget all your preconceptions about it. I've never felt judged or shamed for not being able to do a pose in a class and often come out feeling like I have done a full workout. It takes a few goes to get in to it, but well worth it in my view. If you can't afford classes at a gym or studio there are loads on YouTube you can do at home and are as short as 15 mins.

Bed:
It took me a long time to realise that bed isn't always my friend. Yes sometimes lying down and curling up is great. But I have realised that if I stay there too long, particularly in the mornings then I can often get more and more anxious. On the really bad days you don't have to go far. Sometimes just on to the sofa is enough to stop the downward spiral. But getting up and doing something, anything is often better for me than staying still. 

Notifications:
At first I just turned off any news apps. I was finding being reminded of all the bleak things happening in the world was just getting me down. I found it so helpful that I eventually turned of pretty much everything except WhatsApp and phone calls. Now if I want to see something I choose when to engage with it. Im not constantly being reminded about what I've missed out on, what wonderful lives other people appear to have or what negative things have happened around the world. 

Talking or writing:
As a guy, I have never been much of a talker about anything to do with feelings or emotions. I don't have a huge amount of friends or people I can talk to about things either. It took me a long time to realise that expressing the thoughts in your head makes them float away. I'm very grateful that I can afford a therapist, but when I didn't earn as much I just wrote it all down instead. I don't think it matters too much who you talk to, or if you write it down or say it. But getting those thought out loud in one way or another so often helps them to release and just... Disappear. 

Mindfulness:
Again, sounds hippy but it has worked really well for me. Until I started doing this I never realised how many negative thoughts fly through my head. Or how quick they can spiral. Someone beeps there horn 2 cars back and 5 seconds later I'm half convinced that I'm about to be the victim of a road rage attack. But just sitting and focusing on your breath (but there are alternatives) for a while each day has trained me to notice my thoughts. Now someone beeps their horn 2 cars back and I think, oh maybe they have seen a friend walk past. I use the Calm app these days, but have used Headspace before. They can be expensive but there thousands of meditations and mindfulness sessions on YouTube you can use. It took weeks of doing it regularly for me to see benefit, but it did come. 

Accept it:
This has been the hardest. For me it's like ultimate mastery level. The concept of accepting anxiety was alien to me for so long. Why the hell would I was to accept something that makes me feel so terrible so often? I have a great therapist who has slowly helped me come to the realisation that fighting against it, makes it worse. It's like a Chinese finger trap, the more you pull away the worse it gets. But when you accept it, it calms right down and subsides. I'm not there with this one yet, but by simply actively thinking "oh it's anxiety, it's can't hurt me so it can hang out for a bit" I have felt it reduce almost instantly. 

So there you have it. You might find all of it helpful, you might find some, or just one. Who knows this might not even get read by anyone (if you do read it, I apologize for any typos I've missed). 

I hope that this can help at least one person feel a little better in their day to day.
