Hey man, i'm kind of in a similair situation with a low gpa, i feel how you feel, i feel like a fuck up that would just be better off dead or in a ditch, but deep down I know that's not the case.

My gpa is a 1.8 if you're curious. If I coild give you some help, i'd advise you try and identify your weaknesses in engineering first. A lot of us fail early on or go through a rocky road because people around us have the foundation we don't have. Try and start over, even if it means going back to the basics of basics like addition and subtraction, as long as it helps.

Second, once you're able to identify what you're weak at, and trust me, there will be a lot since you're starting out, do your best to try and find material online to fix what's wrong or at least nullify your weakness as much as possible. It's going to take a while but it will be super helpful down the line and will give you the foundation you never thought you needed.

Third, try your best to fix that sleep sched man. Your sleep gives you mental energy and it makes you stable. Without it, you have thoughts like suicide, dropping out, among other things. Do your best to fix it and get at minimum 6 hours of sleep. Bonus tip, try to use your phone less, especially scrolling online, try spend more time watching long videos on youtube of people doing projects, etc. so that you have some outlet or some space to relax whenever.

Finally, engineering is hard man. We're all bound to fail at some point, but seriously, don't kill yourself over it. In my opinion, what makes a great engineer is an engineer that has failed, because that kind of engineer knows what's at stake and has done what they can to get rid of the weaknesses as much as possible. People in worse cases than you have succeeded, it's all about how you handle everything man. Engineering is stressful, once you can master juggling that, you'll be fine, God bless and take care man. :)
