Wow. That's a double blow. The first thing is to start with a routine that you can easily do so that it becomes a routine. That might be just walking on the treadmill for 30 minutes to get you in the habit of going to the gym... every day. Once that routine is set, then start picking up weights. Start with low weights and easy exercises, again to develop a routine. A good way to start is with machines only... and set progressive time milestones. The first week it might be only 10 or 15 minutes per day... even if don't feel like it or have a really, REALLY good excuse not to do it. It's only 15 minutes. Start building that time up. A solid workout should last at least 1 hour and no more than 2 hours but work up to it in 10-to-15-minute increments until it's a routine habit. From there, you can then start adding free weights and focusing on specific body parts with more advanced moves to develop your form and physique.
Don't be a skippy and miss a day. You have to build a healthy lifestyle. It won't just happen. For diet, what is your current diet like now? It all depends if you are coming from a fast-food regimen heavy on white bread, processed foods loaded with condiments and sweets and needing an overhaul of your diet or if you a more responsible and sensible eating needing some fine-tuning.
