Non physical punishment?

My son is two, turned two in August. Well he has been super bad lately, he’s torn down our blinds in our room, knocked my tv over (thankfully he didn’t get hurt and the tv is okay) he’s tried breaking my phone that I recently got, he’s colored on the walls, he has done just about everything a kid can do. Plus he has started hitting and just has such an attitude. Before anyone says it, he’s really smart for his age, some of this he doesn’t know better than to do but other stuff he does (like the hitting, he knows it’s bad because after he does it he runs off to another room because he knows he is about to get in trouble for it) I have tried every punishment that I can and nothing works, I have been consistent with the punishments and it doesn’t work, he thinks it’s funny. I’ve done time out, I’ve tried getting down on his level and just trying to explain that whatever it is he did is a no no. I’ve done everything but spank and I don’t want to do that because I’m scared I’ll get too carried away and spank him harder than I should have. I get super irritated and upset in stressful situations and tend to do things out of anger and I’m scared that I won’t be thinking straight and spank him too hard, no I would never intentionally hurt him like that on purpose that’s why I don’t want to spank, because I know that there could be a possibility of me getting carried away. And when he starts acting like that plus screaming bloody murder on top of that and throwing himself on the grown acting like the kid from the exorcist I get really stressed. I’m also a single mom with no help, so I’m doing this alone and going through this by myself. If anybody has tips on what I can do please let me know! I’m just lost and don’t know what to do, also I’m young (18) and never done this before so I’m really just clueless as to what I should try next.
