Thank you all for the replies!

It seems like I'll switch into a 5x5 routine. I think I'm going to hold off though since in late June and July, I'll be on vacation for 3 weeks.

The only supplements I'll ever use and will be using is whey protein/muscle milk. So I'll check out Starting Strength and add some isolations maybe or make my own 5x5 routine focusing on the compounds and add isolations?

And also, I heard from doing a bad routine for a few months you can shock your body or something and it can stunt future gains? Is this true? What if I take 2 months off, which I'll most likely do since if I start this week I'll only be lifting for like 3 weeks then I'll end having to take the 3 weeks off in late June.
