Speaking frankly the human psychological behavior is to bring laziness to you and to your thoughts which in turn will slow you down from bringing any change in your body. The overgrowing fat will only accumulate more unless you start to believe in yourself that your work out will make a difference and that commitment and endurance will surely show off in some months.
In order to bring a change you have to exercise and take the right diet and you will surely start loosing that extra weight from your body. I wont say that from tomorrow start doing 50 push ups, 50 chin ups and so many other exercise which will change your thoughts on the first day only. I think just start with the minimum amount of work out so that you won't feel any difference in your daily schedule in the beginning. Gradually you can start adding up your exercises and other stuff which can help you to shape up yourself and you will start loosing fat.
The time is for you to decide, if you have hope you are alive i can say that very well. I believe you can change your shape otherwise you wouldn't have come so far searching for stuff to learn so that you can turn the things around. Well you must know you are a human being just like others, humans have reached an impeccable level of understanding things, discovering and inventing things. You are from the same species. As said already let it start with a minimum not with maximum. Bring a little change gradually it will add up and you will see how it will make a difference in your outlook.
God also likes to change things gradually, implement changes gradually not at once. Start doing exercises, get a better diet plan and work on it. See how things go for a month or two. I am here always to help.
