I have had similar ideas/thoughts, when one is alone, inside one's own head for a long time one's imagination and subconscious (and any drug effects) can really do a number on one; it's a sort of sensory deprivation!

Call a friend, relative, anyone at all and get out of your room and into some sort of treatment plan for your drug problem and less isolated. "Feelings" may or may not have anything at all to do with reality, they're related to our thoughts/words and, right now, your head ain't working right. Get out and about and re-evaluate what you think later, when you are more balanced?
