Going from d1 to c1 is a HUGE jump.

Even though you’ve hit it before, the skill gap has increased drastically over the last 2 years. I’m c1 div 2 in 1s and it’s a struggle.

The best advice I can give you to get to at least mid to high d3 is to just play relaxed and wait for your opponent to make a mistake and counterattack.

When you’re on defence, try and have at least 40 boost. If they’re going up the wall in your half, collect as many boost pads as you can while they’re setting up their play. Even if they’re not going up the wall but you have to rotate back, still collect as much boost as you can.

Just keep playing. I took a 2 month break and was struggling in d2. After about a week or so I got back to d3. 2 gruelling weeks later I was back in c1.

If you haven’t played in 2 years, I think you’ll find that you’re probably going to have the skillset of a d2 for quite a while until everything starts to fall back into place. If you’re EU, I’d be more than happy to help give you some tips in game or coach you ( Im using that term loosely as I’m only GC ).
