It sounds like these magazines are causing you undue stress. Give yourself permission to just throw them out. You enjoyed them when you got them and you looked through them. That is enough. You are taking care of a sick person - you do not need to call around to quilt guilds, Libraries , or thrift stores to see if they will accept them. (I work at a library- very few libraries have the space or the staff to accept a huge donation of old magazines). Put a bundle out for recycling whenever you can, be good to yourself. It is ok just to do what is easiest - they are only magazines.
