Is this molestation?? My god i wanna die

I agree with everyone else. However your reaction may be a concern. When this happened you said you could not eat, sleep or stop thinking about this. Yes it is a validated issue, but it sounds like you blew it a little bit out of proportion and were really driving yourself insane with worry. You may have an anxiety disorder. If I were you I would have a session with a therapist, not necesarily about this incident but about worrying and guilt in general.
