Dealing with Paranoia in Social Situations

Listening to music makes me feel more vulnerable to some one sneaking up on me 😰 I've found that carrying some form of protection (pepper spray etc -where legal, of course), trying not to go anywhere alone (never at night), crossing to the other side of the street when I see someone coming towards me, trusting my gut feeling no matter how socially awkward it may seem, and keeping my phone unlocked with a "9" already dialed when I'm really feeling worried. I haven't been able to yet but I think taking a martial arts course would give a sense of empowerment that could help too - I'll post about it when I get into one :-)
