Optimistic?

Insecurity is born when something bad happens, with no warning, right when you least expect it. The first 49 years of my life were liberally peppered with these things.

I have developed a sort of shield that protects me from this sort of thing now. Part of it is to avoid people who don't really like me and part of it is to stay away from people who lie, because there are people who lie just to get what they want, knowing they cannot, or will not, do what they have promised to do.

I am not strong enough to deal with these people.

I am a naturally trusting individual.  I tend to find the best in the worst situations, hoping that will give me a way to stay grounded and not plunge into those very dark places I know are right there waiting for me.

Insecure and naturally trusting are not particularly compatible no matter where they meet, but perhaps they are found together in mostly true optimists?
