Going to the gym late?

I'm 17 6'0 and 195 pounds right now. I'm a shy person so I'd feel awkward going to the gym in the afternoon (it feels like everyone's staring at me, probably all in my head) I've been doing Independent Study this semester because my bad grades and the past 2 months have made me sick of my lifestyle...I mean I still sit at home and all but I'm definitely doing more (don't have a job, looking to do some community service soon) So the other day I started walking my dog more instead of 20-30 minutes a day, I started walking her 15 minutes in the day, 20-30 in the afternoon, and 10 at night. Better than nothing! Anyways I'm trying not to eat bad and lately I've been trying my brother's healthy foods which aren't actually that bad Yesterday I decided along with eating less junk and walking my dog more that I should check out my apartment's gym. It's 24 hours so me being the awkward shy person I am I went at 12 AM :laugh: I spent about 15 minutes on the treadmill at 3.8...at the end losing about 80 calories. I went on the bike for probably 5 minutes to try it out. I did some basic lifting but not much. Now today I went again around 12:30 until 1:20 :happy: I planned on going on the treadmill for 20 minutes today but I decided **** it and went 30 minutes...lost around 170 calories when I was done and I did some basic lifting again. After that I went on the bike for around 10 minutes and lost around 30 calories. Now should I stop going late or does it matter? I think I'll be more comfortable with it in a few days. I also started having just 1 cup of coffee in the morning instead of my normal two which I think should help Any suggestions guys? Help THANKS!
