Bro of course it's hard, you're trying to go from being too scared to talk to anybody, to talking to 200 girls...you're setting an impossible task.
Why not start with "can I leave the house and talk to one stranger today". Just ask someone for the time at a local store. Repeat this a few times. Then, try it on a girl you find attractive. Then, try talking to an attractive girl and being playful. Then, do the same but try to close the conversation with an arrangement of a future meet/conversation.
Don't set yourself a goal so unreachable that you won't even attempt it. Start small, and keep growing a little bit every day. Before you know it, you will be huge.
