OK I've been feeling a little down lately, I'm thinking it was because of me yelling at my g/f then she goes and says its because of her and I think it's a combination of stuff, I'm thinking it might be caused by my absence of bowling, I've been bowling for like 6 years now and I haven't bowled in like a month and I usually bowl at least once a week, and in thinking that might be it but I'm not sure, does any of this be the cause of my depression?
