Hey there, thank you for answering my post. I too have lost magick in my life due to mental health issues and hope someday I can find the answer to what I am looking for. If you ever need to talk just let me know, as I could use a witchy friend right now. Good luck to you and may your journey be light.
I gotta be honest with you, I saw the notification for this when you posted it and was really hoping someone else would answer because I've been feeling like this for a while.
I'm not sure how helpful this is for you (it wouldn't be my favourite answer if someone told me this, I guess) but I'm trying to listen to more witchy/Pagan podcasts/watch videos and also read wildhunt.org to make it more of a regular thing. I'm a green witch, so I spend a lot of time in nature (admittedly not as much as I wish I would) so I talk with plants a lot. I don't know if this would work for you (or something in your craft you really liked) but for me it kind of helps remind me of magick and how beautiful the world can be. I'm also trying to get back into meditation and yoga, something I stopped doing due to mental health issues.
I read a lot of things for "witchy slumps" where basically they say you need to ease yourself back into it. Enchant tea, draw sigils on your hand, practice some grounding, you know what I mean. I find it kind of hard to incorporate it back into my practice but I think it helps, even if just to remind yourself not to lose touch with your craft.
Honestly, these haven't been the most helpful things for me. I'm struggling with getting back in touch with my witchy side. I really hope that these can give you some insight and help you, though, even just a little.
Good luck, friend.
