Hi Kaley, good to speak with you.
Firstly, you should be proud of making your decision and you know you don't need to feel self conscious around the people in the gym, Just remember that those people didn't know anything much when they first walked in and some of them may have felt self conscious too like you have.
The vast majority of people in gyms will either welcome you or ignore you. There will be the very tiny percentage depending on where you train that will be a bit of a loser about certain people and show themselves up, but you could just suck that up and take it if that ever happened or just report those people.
This is a basic routine that should work for you when combined with cardio.
Squats, 2 sets, 10 reps
Lunges, 2 sets, 10 reps
Deadlifts, 2 sets, 10 reps
Military Press, 2 sets, 10 reps
Bent over Rows, 2 sets, 10 reps
Shrugs, 2 sets, 10 reps
Planks 30 seconds.
You would do that 3x a week every other day.
This is how your schedule could look per week
Day 1. Weights
Day 2. Cardio
Day 3. Weights
Day 4. Day off
Day 5. Cardio
Day 6. Weights
Day 7. Day off.
This prevents you doing 5 days straight and 2 days of nothing, as I think that's allowing too much consecutive taxation and 2 days of your body doing nothing, slowly starting to adjust to it, before 5 days of grind again, which might take the edge off progress potential, so the 5 split days should be better for you.
As for the weight I'd use the bars without any weight for shrugs and the other exercises except planks by adding the smallest amount of weight possible to both bars.
Then you increase the weight used by the smallest amount every 2 weeks and increase planks by 5 seconds a week until you're doing 90 seconds of it.
If you need any assistance with how to eat just ask
