overthinking...

my head is spinning so much.... overthinking continuously.... always falls on the negative side .... how does one switch their mind set to a positive one ... I want too I need help.... my thoughts... I wanna call him.....for what though I just wanna say hi how you doing what if he cusses me out tells me how much of a "b" I am... I always think wrong then it happens... everything goes normal.... I'm not okay.... why do I seem scared what can he do to me except ignore me.... do I need to call... no I just want to for what though what will I say..... well his thoughts are around Her so obviously he can't be so happy will he respond I wanna call him why though...
