Starting to feel the pressure and other thoughts

Starting to feel the pressure of all I need to do to get an A in this Anatomy and Physiology class. It is a teacher I've never had before and she seems pretty demanding. Have lots of assignments due already and mega reading to do! I think they expect 2 hrs of studying a night and that is hard w/ raising a family and other obligations. So, I will burn the midnight oil most nights. I'm a night owl anyway but it will make it hard to get up early some days. If I don't visit your blogs as much or post as much that is because of limiting myself on the internet so I can get some studying in. On another note, the hubby is trying to push me. I mean, I guess, help me by encouraging me to do more exercise. Like when we did the 16 mi. bike ride, he says 'soon now you'll be ready for longer rides' and 'what is your next weight goal'. (I know he wants to help but I just want to share thoughts, not have him find a solution to my wt issues, I think it's going fine and I'm making progress) Sometimes, I share with him what weight milestone I have made as I don't share it with too many people besides mom and sister and you blogger friends out there. He wants to push me to work harder and faster. He wants me to do triathalons cause he's into it big time. I told him that is not my dream right now, getting weight off and becoming healthy is. Heck, that may never be my dream. But on the other hand, I actually had entertained the thought of doing the danskin women's mini tri next August in Seattle to help raise money for breast cancer (a close friend is fighting it). It would be I think a 1/2 mi. swim, 12 mi. bike or more, and 2 1/2 mile run. I think it could be doable but I'm totally not a runner. Never have been and never really liked it. I can do the swim and bike but I'm not speedy. Anyway, I'm toying w/ the idea of buying the book 'couch to 5k' that I've heard about that gets you jogging. I feel it's hard when I tried once a few months back; just the extra weight I still have on and have always hated the bounce (in the chest). If any of you ladies out there are amply gifted in the chest region as I am you know what I'm talking about. Of course, when I was young and in jr. high/high school we had to run as part of phys. ed so I know it's not impossible. I see some websites of women that have lost a lot of wt and have become runners or are doing tri's. One you may want to check out for success story is 'MsTeecher.com'. I'm not sure I can make the giant leap it would take. I'm nervous just thinking about it. Anyway, just venting a little tonight, post is all scrambled...thoughts everywhere but too tired to fix it! Hope everyone is having a good week.
