I have few friends, but the ones I do have are my 'brothers in arms', we have complete trust and faith in each other because we've been through many tough and good times together. I cannot imagine sustaining myself on a toxic relationship, especially when my own self-esteem is rather easily reduced. I do not think its a bad thing to regret not having more friends, quality is infinitely more useful than quantity -- and even if you're by yourself, so long as you allow your good qualities to shine, then you attract good people into your life. One has difficulty forming these new bonds when one invests ones efforts in a relationship which is doomed to fail.
