Home again for a few days...

Okay so last night I came back home for a few days but I'm feeling the anxiety. To reinforce that what I am doing is a good thing I have been doing research on what is an ideal body weight for me. My anxiety I think comes most from wanting to get into a workout routine to be active and not knowing where to begin. I think that's my biggest problem right now. I haven't worked out this week at all and it's taking a toll on me. Yesterday I ate very well but after feeling my stomach in pain at night I started to freak out a little. I get down on myself that I am eating desserts because I want to gain healthy weight and I feel that is not going to help me gain healthy weight and not working out is making it that much worse. I need to get myself involved in something. I was thinking of trying out the Wii Fit today and maybe running to Target to get a dance DVD. I have my resistance band, free weights, exercise ball and workout mat...now what do I do with all of it? Finding a workout routine that is right for me is overwhelming me...ugh...I need some motivation.
