Obsessed

I've been doing this for like 7 weeks, and it has consumed my life. I have so much work I'm supposed to be getting done on my computer at home, and literally I'm on this all the time or looking up food or exercise information. I literally plan out my days of food eating the night before. I'm obsessed. When I can't work out all that I want to (tonight, for example, because it's raining), I feel gross, restless, and anxious-- even though I already swam for 35 mins today and am not over my cals at all, because I made sure I wasn't. I want to do more. Part of me is like that's really good, and then I think I'm becoming seriously obsessed. I just want to do everything the healthy way. The ultimate healthy way. I wasn't eating back enough exercise cals from before and was netting too few, so I'm slowly trying to work my way up to healthy and maintainable level. I only have about 6 more lbs that I want to lose. But it's not about the number. It's just about being healthy, to me. I want to treat my body 100% right. But literally, all day, every day, no matter what I'm doing, I'm always thinking about food and exercise. I can't let myself not care anymore, which is kind of taking a toll emotionally. It's hard for me just to enjoy the ice cream, even though i know I deserve it. It's hard for me to say, ok, burning 300 cals today was enough. So, although I'm trying to do it healthy, I'm not sure this is mentally healthy for me. How do you balance the two? Any tips on how to deal with this? Do you think it will go away? It hasn't so far in 7 weeks. I feel like this has consumed my life and thoughts, which I can't let happen once I get back to college in a few weeks..
