First of all, your situation is difficult even when you're not trying to maintain or lose weight. Moving to a new place, especially when you don't have control over so many things is very stressful. If you were originally from a very different environment, moving to CA can seem like not only a new state, but a new country.
I would say concentrate on damage control and harm reduction first and foremost. Don't worry about losing weight, but focus on getting nutrients, keeping as many of your former habits intact as possible, and not gaining.
To that end, you may want to consider the following to help with your logistical problem:
- Subscribe to Freecycle and Craigslist in your area so you get early notification of free things that may help you or can ask for things (like a bicycle or refrigerator).
- Look into local "welcome wagon" or community services to see if there is someone who can provide assistance in getting settled. Not having a refrigerator is a big deal and there may be an agency that can help you out. Call around and see what people will do. It may seem embarrassing, but those agencies are there to help.
- Check the public transportation system to see what might work for you.
To help with the food acquisition issue:
- Look into buying food by mail order. Walmart is cheap and they do sell some food. Other places are more expensive, but will also deliver. Amazon also has food, including a lot of diet food.
- Investigate shelf-stable food (that is sold in single-serving ready to eat packages) and look into what will "keep". Things like oatmeal in a cup that you just add hot water to, fruit, and most vegetables will keep outside of a refrigerator. This is not ideal nutritionally, but better than gorging on fast food.
- Again, check local public services to see if they can help you with getting out to shop. You may be able to volunteer some place that will include shopping for the elderly or disabled people and get your food at the same time. This is, however, a long shot.
To deal with the boredom:
- Plan to be bored and have a plan of action at your job. For example, when you want to eat, have a list of activities that you will do instead. This can include writing in a diary, reading something which is appropriate at your work, doing some small maintenance task that is acceptable for your position (get up and straighten or clean something), sort something, do some stretches with your legs under your desk if you can do so without being seen, go to the bathroom, or do an easy or complex mental exercise like play back a scene in a T.V. show, book, or movie you love and have seen many times from beginning to end. Use the boring time to think of things to do when you're bored.
- At home, if you're bored, the obvious answer is to take a walk, get to know your neighborhood, and see what your options are. If it's in walking distance, the local library is a fantastic option. Also, in my area and those near me, there are lists of free activities online (movies, musical performances, author readings, art and craft festivals, etc.). Search for "free activities your area's name" and you'll eventually find such a list as well. Go to those things whether you're completely comfortable or not. You'll feel weird at first but eventually you'll feel better and less bored. Develop interests. Don't wait for them to find you. Interest is something we cultivate, not magically possess.
Finally, if there is a hotline for people who are having emotional or mental health issues, call it and talk to someone about what you're experiencing. Such hotlines aren't only for people in dire situations (like suicide) in most cases. See if there is a way to find support emotionally. What you're experiencing is very hard and your boyfriend may not be able to provide the emotional support you need since he's not in a new environment (and may not know about weight loss challenges). He may be kind or a lovely person, but some people can't put themselves in your shoes. However, I'd still suggest talking to him as unemotionally as possible about how you feel and seeing if you both can face it together and find a plan of action to help you with dealing with the food problem as well as the adjustment issues.
Like you, I have to know where I stand with my eating for the most part or I lose track. I know why you are gorging on junk when you have it because you are afraid of being insanely hungry later. You need "food security" and you'll have to be creative to work around the things standing in your way.
Given how stressed you must be with all of the changes and limits, it's going to be an enormous challenge finding the mental wherewithall to do anything that I've suggested. Try to tackle one at a time and be patient with yourself. You lost weight before. You can lose it again. Give yourself the time needed to adjust, but do start to make the effort to master your new environment as best you can. Good luck.
