Oh boy I have had so much stress lately, this is very relevant haha.
Exercise - Joining a gym this year has been the best decision for a long time. It's a nice quiet one not a big chain, and I go at off-peak times.
Today I wrote out what major things have been causing me stress were
(things like putting off phone calls due to anxiety, or cleaning that needed doing)
and tried to tackle a few of them to lessen the burden. It definitely helped.
Going to the cinema alone helps sometimes!
I am a master procrastinator for deadlines and things that make me anxious, eventually taking a step, however small, towards those things feels so much better than the short term relief of not doing them.
Also when your mind is going a million miles an hour, focus on trying to calm your physical body. Whether that's with a bath, a nap, exercise, a comedy, anything to try to relax your body and send the message that your adrenal system can calm down.
