You're still a strong young woman with your whole life ahead of you. I know things seem really overwhelming right now, but things will get better. Living with your parents isn't a bad thing. I'm sure they must love you and their grand daughter to pieces. You'd be surprized how many adult children have had to move back with their parents because life became difficult.
The universe isn't out to get you even though it might seem like it right now. Many people are having similar problems right now. You can't let that get you down !! I was laid off from my job last year. I am still looking for a full time time. Do I get depressed ? Yes, there are days when I get depressed. BUT... I'm staying positive and you need to stay positive too.
Look at all the things that ARE working for you. You're living with your parents. that means you can save money for your own place later. Living with your parents gives you a chance to look for a better job or go to school to take classes.
You can regain your health. You can lose weight, but you have to take things slowly. Life is going to throw roadblocks in your path. Taking a detour now and then isn't such a dreadful thing. You may not arrive at your destination as quickly as you think, but you will still get there.
What to do ? Take things slowly. don't try to do everything at once or you will end up frustrated. Start with some simple changes first. Example, if you're not eating 6-9 servings of fresh fruit and veggies, set a goal to eat 2-3 servings each day for one week. if you're not drinking 8 glasses of water, set a goal to drink 2-4 glasses each day for one week. if you're not exercising, don't try to do an hour a day, set a goal to take a 30 minute walk each day for one week. Once you've achieves those goals, then you set new ones.
And that's how good health starts. It doesn't start with an "all or nothing" mentality, it starts with a few simple changes. One small change CAN change your life !! You have to believe that because it really is true.
Don't worry ! Everything really will be okay.
