i know how you feel. its frustrating when people get in your face when all you want is to be alone. unfortunately most people dont understand this feeling so dont realise it has an effect on you.

dont make up excuses, just say to them straight "i dont fancy being out tonight, i just want some quiet time" and then go home. and if this boy texts you things like that again, just reply saying "sorry, i didnt feel like meeting up with you, i just want to be left alone for a while" and make them aware that it isnt anything personal against them and you appreciate their concern but youd rather be left alone when you feel this way.

it is really frustrating, i know but you just have to be honest with people. then they will be there waiting for you when you need them and they wont feel bitter about it.

take care and dont stress about it, we all need some time to ourselves occasionally. they should understand that.
