You’re not over exaggerating. You’re not too sensitive. You’re not too much. If it hurts you it fucking hurts you. If it makes you angry, then it makes you angry. There’s nothing wrong with you for feeling.
When SpongeBob turns 20 he will turn into a real boy and you will all have to watch Human Bob and enjoy it. He turned 18 today, so you have 2 more years to sort out your feelings.
