I grew up super poor as well ane while I'm not like this at all my sister sure is .. it's like because she never had anything as a kid ... She's always afraid she'll be back to square one and to her the more things she has the further away she is mentally from our broke down childhoods... so when an opportunity arrives such as bags of free clothes she tends to over indulge taking way more then she needs because of some underlying fear of having to go without. Try not to take your family's response personally it's definitely not about you personally at all and it's more about your family's unhealthy over indulgence on opportunity when it presents itself because at one point in time they had nothing and more things = more security ... Just my 2 cents try not to judge them too harshly
