I can totally relate to it. They will make fun of you only to tease and as long as you are getting affected by it will only motivate them to continue. Just keep smiling and if you have anything funny then do that as well.
Slowly they will stop.
I keep smiling but then too it continues. if i do anything funny they do it more
thank u yolo
Friends are necessary for our mental wellbeing. If you are just a source of fun for them and not getting anything in return, then its toxic for you. Try to find some new friends who are able to understand you.
If you are good friends then try to find out the faults in your actions on which they are mocking you and try to improve on it. If there is no fault then be yourself and try to ignore them. They will stop eventually.
