Our parents have scared us into getting healthy

Hey everyone i dont have a question just hoping to inspire someone who is looking to get healthier.
At christmas we had my father in law visit for a week, which was fantastic we hadnt seen him for over a year. Now i love my fil to pieces and get along great with him, however his health really scared me. He is very overweight, he has already had a stroke and both knee replacements and drinks like a fish. After he left it got me thinking about my own parents , both of whom are type 2 diebetics, and both have had major heart attacks and surgeries and my mother also drinks like a fish.
Looking towards my future scared the shit out of me. I did not say anything to my husband about how scared i was about the path we were headed towards. You see he too was a big drinker every night after work and even more on days off and weekends. It stayed in the back of my mind and constantly came to the front that i should do something now to change it.
A few weeks later my husband changed his role within his company so instead of being active for 10 out 12 hrs a day he would be sitting at a desk for 10 out of a 12hr day. Before he started this new position he rang me one day and said "hun im going to be late im going to the gym with a guy from work( who is also current training to become a PT.) because i dont want to become my dad. Yes!!! That was the last bit of motivitation i needed. I wanted to support him and encourage him but i also wanted him to do the same and not say "oh you dont need to do anything" . The next day I started walking after the kids went to school i put my toddler in her stroller (which is massive for someone who had pnd and anxiety and had ppl who didnt have pnd or anxiety tell me like it was no big deal when she was a baby and only slept for 5 mins at a time to do this....yep thanks champ you try it first when you are in my headspace.) I walked for a good half hr and was starting for feel better physically and mentally. But i would look in the mirror and still see things like my 4baby belly or my grandma arms and i was still eating crap. No breakfast, sometimes lunch and bugger all for dinner. Not to mention i wouldnt drink anything but softdrinks or juice or flavoured milk. Yep i was still headed down that dreaded path. I asked my husband to show me the exercises he was given, i rang my sister who loves working out and is a boxer and asked her for advice on where to find exercises, and what to eat. The thought of entering a gym makes me want to hyperventilate and honestly i could not afford it even if i was cool, calm and collected about it. So i googled and i searched fb, and i youtubed and i pinterested and i instagrammed to find exercises i could do from the comfort of my own home. There honestly is a tonne. I invested (weeelll my hubby did as a birthday present and yes he was worried i would be offended but i saw it as encouragement) in a set of dumbbells. I started replacing my walk time with work out time but with a toddler it was near impossible. So i get up before the kids when the house is quiet and workout 6 days a week now. Some mornings especially if my bub has had a crappy night the struggle to get up is oh so real. But I do it. I push through the "i cant be bothered today moments" and i just do it. (I sound like the nike ads lol) Other mornings like this morning i realised that it has just become second nature and just part of my routine. My hubby after a 12/13 hr shift will finish work and instead of having beers will work out instead. He has gone from from drinking every day to 1 day a week!!! I have not had a sugary drink for weeks now instead drink so much water that i pee like im 9mnths pregnant. I am still working on my eating habits but i am eating breakfast now. I dont deny myself anything food wise but i do question myself if i really want it eat something that isnt very good. We have been doing this for about 5 weeks now and i have noticed such a diffence in myself not just physically but mentally as well. I have more energy to get through the day. I face stressful situations head on instead of burying my head in the sand. I have lost just over 4kgs and about 10cm from my waist. It maybe to late to change the path but I am sure at least we have certainly slowed it down. We are both loving our workouts and its just become a part of our routines now. I havent spent a shitload of money to join a gym and I have made time to exercise. And if i a self confessed couch potato can do it Im sure anyone can.
