I am 25 years old and have a relationship with a girl from 5 years. But I am very scared of some situational thoughts which can't be happen like I am good with everyone just because no one will make a connection with that girl. Feeling very scared and anxious because of these thoughts. My mind thinks that if I will not be good enough with anyone like my friends who knows about her then in future he will make a connection with my girlfriend. My thoughts are making me mad feeling very insecure. What to do.
