Welcome to the community Mar and a huge congrats to you for your 3 days! I know the beginning days are super terrifying and exhausting. I did spend a lot of time sleeping and playing on my phone on mindless games i had downloaded just to keep myself busy. Hang tight love - it does get easier.
For me keeping busy was essential - i did try to get out and walk in fresh air when possible. You are not alone in this my friend - take some time to read around the threads. Reading other peoples stories really helped me out and let me know that i was not alone in my journey.
One of my favorite threads is Checking in daily to maintain focus #60
