I second what the others are saying - you're not alone in this at all. This is often a great site for support and information, and probably people here have gone through similar things at one point or another.
I also agree that something you might want to look into is talking to someone professionally about your anxieties, especially if your partner and friends are not able to offer support with that. Talking about things like that often helps. It's a way to sort through things and deal with them. And it may be that the way your partner deals with her fears is to not talk about them (I know, because I do that a lot - not super healthy, but it's my knee-jerk reaction and it's hard to break). She may not be too busy - she might just be really worried about the same things and handle it differently. I say that because it may be true, and because sometimes it's helpful to know things like that aren't out of a lack of concern, but rather too much concern (overload, basically).
A lot of people here will be able to identify with not having anyone in their real life to talk to. Many of us don't for various reasons. I have no support in my real life. It works out surprisingly okay (I get a lot of motivation from myself - outside critique/compliments actually throw me off, I've found). I'd recommend maybe starting a weekly exercise or weekly weigh in thread. People go there to chat and report on their progress. If you find the right one for you, it's like a daily talk with people who get what you're going through.
As far as weight loss, it's going to take time and daily work. It doesn't have to be really hard all the time (in fact, if you find a method you like, it really shouldn't be), but it will get tough at times. That's okay, and that's normal. The tough parts pass. Any loss is a victory - quick loss isn't "better." It IS worth it, though. Just do a bit at a time like you've been doing. Going slow and steady works best in most cases. The weight will come off in time if you're fairly consistent.
Good luck, Patricklm82! And welcome to 3FC!
