The bottom line is you are pretty unfit. Fit people can work out just fine.
I like to do short runs. Out here in Thailand at 35C/95F -that's usually a 5k run every other day at around 24 mins and 30 seconds. It's hot, it's humid, I'm reasonably fit but no athlete and I'm 43. On alternate days I cycle 30k in an hour and 15 mins - but that's not flat out because the terrain (and dogs) don't allow it.
Now - what risks am I taking on if I add a fat burner to that equation? Well, I don't think they are small. Not with the humidity, temperature and my age. Neither do I think they are small for am obese 32 year old like yourself who is trying to get in shape. Why on earth take such risks?
For a buzz?
You are also an addict. As an addict you should know that stimulants don't GIVE you anything, then just borrow from some future point. Hence comedowns and hangovers.
There is nothing worse than being unfit and starting to exercise again. It's fucking horrible. On the other hand, you get a nice, natural buzz just by training when you are fit.
You just have to grit your teeth and get fit. That is all. As an addict you should not fall in to the trap of trying to shortcut fitness through pills. You aren't working out to get a buzz, you are working out to better yourself.
