I apologize, me again. I cannot find my previous message and I think it got removed. If an admin has the ability to remove me from this group, I would really appreciate it. I do not have the ability to remove myself.
There should be an option to do this at the top of the group homepage. Beneath the group title and description it should say "You are a member" with options to Edit Membership or look at Group Info. If you click Edit Membership, at the top of that page is a link to Leave Group, which I believe is what you're looking for.
Thank you!
