Mom wont let me get rid of old toys from when i was akid. what to do?

Pack the stuff into boxes and move it into your mother's bedroom. Tell her outright that you're embarred, and that you don't even want to have friends over because you think your room is clustered and shameful. If it continues then talk to another family member. Your mother may genuinely have a hoarding problem that revolves around you, and she may need help.
