I am over 18 but the thing is I'm currently without a job (Been looking for a VERY long time with no success) and I live at home and going to school full time. So that line is a very thin one. They think they can boss me around (as I'm under their roof I guess they can) But I need my independence. Like i said VERY thin line.
Chica,
If you are living at home, you definitely need their support, not their approbation. I would recommend that you spend some time thinking about what sort of support you need from them. Could they help by keeping healthier foods in the house? Or by going for walks with you? (Or by leaving you alone when you got for a walk!

) Or by offering you encouragement of a different sort? I would really sit down and think about that stuff, and then sit down and have a chat with them - a heart to heart - telling them how difficult this is for you, how hard you have to work to lose weight, how you want it to work, and ask them to partner with you. Ask them for their understanding and hopefully they will give you what you need.
I'd also say, too: If you are working out to the point of being so sore that it takes you several days to recover, you are doing too much and should maybe pull back, but exercise more regularly at somewhat lower intensity.
If you can only walk ten minutes twice a day, you are still getting in twenty minutes of walking! (If you can only manage five minutes - twice a day is ten minutes. Three times a day is 15!) Spread out the exercise, do it in small segments, focus on increasing your time a bit every week.
Commit to that five times per week and you will find the back pain and other issues that limit you initially because of deconditioning will start to recede. I know how hard it is, but hopefully that will help you start building up stamina!
