Vent/advice/overeacting

So i know this is silly maybe but im bummed today and feeling depressed so things are really bothering me today... my bf for the past week has been real clingy which is not like him so I was loving it and the attention, he works a job were he can be on the phone and he was calling me throughout the night on his shift which where before he never would even text or if he did it was taking him forever to respond... so I felt on top of the world with all the attention, buuut today he isnt giving me the same attention :( just is throwing me for a loop... I was getting used to all that attention idk what happened or if im overeacting ???
