Hey guys, I used to suffer from depression, I didn't even know I was also blacking out from heart pulpatations getting hospitalized countless times only to find out it was panic attacks. I also begun to develop social phobia. Afraid to meet people even family I would lock myself in my house, oh well praise God I got out, he actually set me free from alot of stuff, but it took me to let go of alot of stuff, I think there are times when we should be alone, however we are wired for relationships.
God intended for us to be that way, designed, true we should be wary of who it is we build relationship with, but there are many more donts there are do's that it could hinder us from actually getting to know people who may actually become a blessing in our lives or even we theirs. For me, since being free from depression and some phobia's has allowed me and challenged me to build relationship with people I would not normally include in my circle of friends and acquaintances. I have bonded with people from my Gym, Church, who I meet at the gas station, pretty much anywhere. Now everytime I leave the house, I actually look forward to whoever I meet whereever it is.
For those of us whose only social avenue is being online, I think if you delve a little deeper, God may actually be building you up to graft you into the right group of people, so that you can grow some more. You know pray and ask the Lord to bring the right people across your path whether they be Christian or non Christian. Just a suggestion.
