Wrestle ups, sweeps and getting to top

I usually play guard and today I was especially tired so couldn’t stand up, but in turn got passed and smashed a lot. I’m happy to be bottom, but after today it got me realising that I need the option to take get to top whenever I want to (against equally skilled people) to avoid just getting smashed. Anyone who is good at wrestling ups and sweeps, is there techniques or is it just concepts like grab a leg and stand up. I know sweep concepts like take away two bases, and can usually get scissor and butterfly sweeps, but I’m terrible from half guard and I have never wrestled up from seated guard . Shall I just stand up?
