You sound super stressed, and you probably should, you have a lot going on and a lot to juggle. I was roughly on the same boat last year, Money problems, family problems, too heavy to do all the cool things I wanted to do, all my friends live a distance from me but I don't have the money to go see them, I was at university, but everyone in my class was young and I was 27. The only plus I had was, I was single, no extra pluming to maintain.
What helped me out was actually a few sessions at counselling, it really helped me with stress management and to clear my head of all the trash I shouldn't of been stressing over. It helped me create a list of things to fix, pay a little here and there to the debt people so that they kept off my back. I graduated university with a great score. I moved back to my home town so that I could build up a friendship with my mum
. I expressed my feelings to people a little more so that they knew how I was stressed out, I was also then letting myself know that it was ok to be stressed. After a long list of things I changed, I felt much better about looking after me! Only then was I able to lose the weight.
I suggest if you felt you would benefit, to do the same. I have lost nearly 40lbs through changing my diet ALONE! I started at 323 and I am now 285 and while I do the odd core exercises with resistance bands at home, as well at walking the dog for 20 mins a day, I am a home office worker. I will start doing a cardio class and a strength training class after Christmas as I will of lost 50lbs by then, and I will be toning the heck out of my body
Just take baby steps in the right direction and you will start to see results. 1lbs a week is a perfect loss rate, you didn't put it all back on in 6 months, so take the next 2 years to really change your lifestyle around and make it sustainable once and for all
You can do it!
