As everyone is saying just eat everything, I was 55kg when I started, although I am slightly smaller than you I had a very small frame.. It's best if you get a program together, as other exercises...
Wherever you are in 6months, if you train hard and eat right you will be in a much better position you are in today, then you can focus on the next 6 months,
Gotta be honest Bro didn't read the full thing but judging from thread title I'm in same boat.. Living with parents, she's renting council house. If I move in, all my savings goes in bills..
Sometimes I'll do 3x10, others 5x5.. If nothing else it changes things up gives a bit more variety between workouts, now I just want to be able to lift x10 that I can do x5
