Struggling and needing some support...

You need to find your own path. Yes friends try to "inspire" each other by pushing each other into workouts that are likely too much for a new-to-exerciser to be able to do. Yes, we want a challenge - but personally, I like a challenge that I know EVENTUALLY I will be able to complete (not feeling completely hopeless, thus losing all motivation).

Why dont you go throw that burger out? That would be even harder, but WAY more satisfying.

Have you looked into Leslie Sansone? When I first started at 250lbs, I could not even do 7 minutes of walking in place without collapsing, covered in sweat. When I first tried one of her workouts, I knew that it was going to be progress - but every move is so simple, it is possible. I know I did want to be able to do Zumba because "Everyone else" was doing Zumba. Well now I can laugh at the Zumba workouts because they are wayyy too simple and "dancey" for my style!

Anyway, find your own path.

Check leslie sansone out on youtube and/or her dvds are often sold at Walmart for like 5-10$ a piece. (Just if you were looking for a do-able workout)

Ive been struggling with weight loss for years. I know how it feels and be discouraged from time to time. The lack of support from people around u as well as lack of knowledge about lossing weight (proper diet and exercise) can make u lose focus on ur goal.
I was almost 120kg when i started and i remember dragging my feet when i walked. I decided to loss weight and when i started i used the treadmill and 1min slow walk was a struggle for me. But in time i increased it to 5min then rest for 1min then start again. Did that for 3months and lost alot but couldnt stick to the diet i gave myslef (onions tuna cucumber and crackers...i wasnt eating properly)

Its not gonna happen overnight so dont give up. There are really times when i did give up and tried fad diets and pills, those didnt do me good.

Joining MFP and tracking my food and getting support from those like me was great help.

Weight loss is not an easy process for a lot of people; unfortunately it takes time, work, and will power. There will be days where you think 'I will never achieve this', or days where you think 'I just don't care, I can't be bothered'. That's just life, we all get those! The best advice I can give is take it day by day and slow and steady. We build up eating habits over months, years, even a lifetime, and they can be very difficult to break. So, make small changes, take it slow, celebrate the small victories and remember; you are doing this for YOU. Don't compare yourself to anyone. Do what makes YOU happy.

One of my favourite sayings, which I tend to post quite a bit but really helps motivate me is something along the lines of 'even if you only lose half a pound a week, that is still 26lbs in a year; don't give up'.

Everyone felt helpless at some point. At least, when we started.
I agree with what's been said above, it's a lifelong journey, not a quick fix. Take it one decision at a time.
Have a look at all the success stories here and you'll see that everything is possible.

Basically, you just have to start....something. Either it's having a (long) walk, fixing a first healthy meal, cleaning your house from as much crappy food as you can, anything.

If you have a lot of weight to lose and never actually tried to do it THE RIGHT WAY (meaning healthy diet with enough food and the exercise you can manage) chances are the first pounds will drop off quite fast. This will encourage you.

Along the way, you'll find out what works for YOU. The only thing you can't avoid is right eating and moving. But what kind of move doesn't matter, especially when you start.
Walking is a great way to start. It doesn't hurt your joints and the progress (distance, length, path) is pretty impressive. That could be enough to put you on the right track.

The hardest part is what I call 'Mind Fitness'. All the emotionnal crap that makes you give up, made you gain weight in the first place has to be dealt with along the way. But it is manageable too.

Just start.

I know how you feel. I've been trying to lose weight for a very long time (early teens) and while I have been successful at losing 20lbs, etc, now is the time where I have my head on straight and I'm doing it the right way. It took gaining 30 pounds in a short period of time and my doctor putting me on a low-fat diet to realize that I couldn't fool myself anymore. Do I have pizza or fast food? I do. VERY rarely. I've decided that I want to not only lose weight, but be healthy so I am changing everything that I eat (including not eating fast food anymore). Also, have you tried looking on YouTube for different Zumba classes? I can't do high impact workouts right now but I do do Zumba.
