Drive thru and saying thank you LOL

Drive thru and saying thank you LOL “Thank you” is one of my biggest block words it’s the t sound that gets me I literally have to say “preciate it” or say alrighty thank you to get it out. A lot of times Im so emotionally drained that day due to other parts of my life that I just grab the food with no answer becuz fuk talking sometimes but that’s hard for me to do since I was raised with manners. A lil add on, whenever people hold the door for me and I block with no thank you, that is the worst feeling in the world knowing ur stutter is making me act out of character.
