gosh... i can relate.... i remember spending hundreds on books.... i went to a bookstore once, and i didnt even have a book i wanted in mind... usually, when u go to a store u know what u want.... at this time, i knew what i was doing... i was already aware because i did this before... the whole spending thing....
so... im at the store and think, maybe i should get this one book i had in mind back then.... i pick it up but stop myself.... i think about it for like 10-20 minutes, then just leave... i go home, a day later i check my bookcase, and it was there... i had already bought it a long time ago... and i didnt even know.....
ive bought duplicates a few times already, so thats when it really hit me to find the source of this and how i could control myself better.... learned my triggers, learned how to cope, learned how to stop myself.. that was almost a year ago, so ive only really bought a book maybe once or twice now... and of course, i read them..
