Need help

I'm 21 5ft 3 and 180lbs

I have no motivation to exercise. I have a 1 year old and a boyfriend thelat eats for England so all my meals I make are quick and a bit unhealthy I don't have the money to go to the gym or to do the diet supplements like juice plus and that

I'm wanting to get to 125lb or close to that as I hate my body and my depression is taken over again I can't exercise longer than 10 minutes before I feel like I'm going to pass out so I don't exercise at all or I don't feel like doing it please help
