Losing too much weight?

I am psychologically bottoming out. My lethargy and apathy is growing by the day, I feel weak and so completely not myself. Generally I'm not sad (though I have those days), but it is more simply not caring about anything, which isn't like me. I don't think it is depression, but rather withdrawal from my almost daily endorphin rush from going to the gym. It is a very real thing, developing a dependency on those chemicals, the rush and totally pleasurable feelings you get from killing it at the gym and pushing your body so hard. I feel so completely not myself, and truly it isn't the isolation that is making this so difficult for me. It is the withdrawal. 

Apart from the lethargy and the melancholy, I also am suffering a pretty significant loss of appetite. I'm having trouble eating enough simply because I'm having a mental block around eating when I'm not hungry so I'm frequently having up to 5 points left over at the end of the day I just don't get around to eating. I got harped at a bit this weekend that I need to eat more, and that since I have lost and am losing a significant amount of weight. I weighed myself over the weekend, and have lost a significant amount of weight, even with the cast on. My parents' scale read 245.8lbs, which I actually think can't be right. Regardless, I have been told I need to take a multivitamin with extra iron. Fine. I think the problem is being over stated, some of the weight I have lost since the surgery is muscle mass, but I will concede that I have also lost fat as well. My parents are worried I'm not feeding my body enough to be able to heal effectively from my surgery. I think I'm probably fine, that I am eating a sufficient amount, but I will do what I am supposed to and try eat more.

That said, my recovery is going okay, and I am going to try going back to work in my office tomorrow. It will be really nice to start moving towards a normal life again. However, I have been strongly suggested to call my surgeon because my foot turns a horrible colour when I stand up. It should not be discolouring this much a month after my surgery so I'm going to call her office and see if I should go back to the fracture clinic or what.
