Supernatural S9Ep12

I'm watching this episode with Garth and I realize that Sam doesn't really have any friends except Dean and it saddens me because Sam is worthy of friends also. Cass is his friend but if he had to choose between him and Dean he would choose Dean in a heartbeat. I mean, Dean is cared for for many people but Sam isn't. I mean,at some level they like him and stuff but they are only close to Dean. I feel like Sam was made to suffer his entire life...
