Thinking of quitting

My son will be 12 weeks next week and has been exclusively on breastmilk sice around week three. With the help of all uou wonderful ladies on the board I have made it this far and this seems easier than before. The pain is not as bad either. And yet I find myself sitting here thinking about quitting. I promised myself I would not quit befor going back to work, next week will mark three weeks back in the office. I promised myself I wouldn't quit while still dealing with thrush, that is gone. I told myself I would try and breast feed again and have been feeding once or twice a day for a little over a week. I got the pumpin pals this week and have been disappointed, pumping takes so much longer with them. I guess I am just tired. Tired of having to figure out how to squeeze in pumps at work when I am double and triple booked all day with meetings. Tired of the anxiety of how much or little I am producing. Tired of worrying about missing a pump session, sleeping an extra hour, if I am taking enough herbs. Tired of eating oatmeal. Tired of being too tired to exercise or spend time with my husband. Tired of having to tell my other two boys they have to wait while I desperately try and get 3 or4 oz from a session. I am tied of not losing anymore weight ( I thought that was supposed to be a perk of doing this!). And most of all tired of feeling guilty for wanting to stop. Thanks for listening.
