Hello! Been quite a while since I've been on the forum, but it feels good to be back.
I have had some recent dilemmas contacting my hellhounds as of the past few months. I've also slacked on my witchcraft path a little, as well. Does anybody have any ideas on how I can lift this block off my energy and hear from my boys again? I haven't felt them in some time, and it worries me. I miss them, and I want to hear from them.
Thank you in advance.

You could try meditation with the vessels, placing out their favorite treats, inviting them into your dreams, or just speaking with them throughout the day...just a few ideas.

Give yourself some time and don't blame yourself. With everything going on in the world it's not unusual to become a hermit crab retreating from everything and everyone. I don't think your Hellhounds are going to blame you for this.
Try to figure out what's draining you the most at the moment and what's providing you with energy. Then get moving. Physical exercise has a big influence on our energies. Breathe and eat conciously.
It's easier for them to get in touch with you, if you're feeling well and yourself.
They're surely picking up your thoughts and worries.
