Hope it's ok to share this here... I've recently set up a penpal group for women with endometriosis.
I first started penpalling while I was going through diagnosis and surgery and I've since realised it's a great hobby if you suffer from endometriosis. You're building up a connection with someone but without having to commit to specific dates and times- something that can be really tricky when you don't know how well you'll be feeling. And you can write a letter while resting/ using a heat pad/ drinking a nice cup of tea.
You can sign up on Elfster: www.elfster.com/gift-exchanges/3b0db173-04f0-42cf-8d4c-735fff01cd14/?join=m2iw
Or @endo_penpals on Instagram.
Your name and address are kept secure on Elfster and are only shared with your penpal. You should get two matches- someone you write to first, and someone who writes to you first. If you'd like more information or you have any questions, just message me :-)
