Dreading coming out of work

In work, I have a positive attitude towards my ability and achievements and always have a "can do it" mentality. But when it comes time to end work and cold approach women outside, dread seeps in and I work a little longer until I can get myself together to face another dark tunnel. As I go outside, I feel like an utter loser that will never be successful at meeting women, the complete opposite of how I feel at work. Replacing "cans" with "can'ts" and obviously depressed, I put myself on a 3 minute timer to go approach a girl or else I'll be forced to choose the first woman I see after that and talk to her. That strategy is pretty much the only way I'll get to talk to anybody or else I will delay it forever, so I just dread going up to a girl I don't even find that attractive and then awkwardly making a greeting and getting brushed off. I've been told that watching porn and masturbating could be causing my loss of interest but is there anything better I can do? Thanks.

Only way to get more comfortable is to do it. Join a club or activities where people socialize. Get used to introducing yourself and talking about what you do. Just focus on having conversations. It is the First step. Cold approach at a mall is jr high double dare crap...
