I dated this girl for around 11 months and was head over heals for her and loved being with her but around halfway through our relationship when I drove if get sick in the stomach and my appitite would suck and then we broke up and it kind of got better about a month after the break up I could eat but it was still kinda bad but then like a week ago I started talking to this other girl and we hung out today and I felt sick after she left.. Anyone knows what's wrong... Anxiety maybe??
