Not let go of interesting people I meet

I donno why but everytime I meet a nice guy, this little voice in my head takes over which tells me “how could this guy like me…surely there must be someone better out there for him…someone way better than me”
I am usually a confident, outgoing sorta person. But when it comes to my appearance, I do tend to think I am anything but perfect or beautiful. I just don’t like the way I look. I know it’s all God-gifted yet I feel like I’m a person with the lowest self-esteem in the world.
It’s this attitude that makes me want to drive away the guys who seem to like me. I just end up messing things…on purpose…and losing out on love that comes my way.
I don’t know if I’ll ever get over this. I need HELP!

Every once in a while I meet some really interesting people…but somehow I tend to lose them after sometime. I wonder why! Maybe it’s true when they say..some people are a part of your life only for a season.
