Sounds like you have made some changes recently (e.g., paying down debt instead of running it up), which is good, but at this rate you're going to be tight for a normal retirement, much less ER. Some specific questions/thoughts:
1. Take the advice about slashing the phone bill.
2. Why is your insurance so high on such an old car? Call around and see if you can cut that back quite a bit -- a lot of folks omit all but liability, but usually you do that only if you can afford to cover a replacement vehicle yourself.
3. You top priority is getting the CCs paid off before you start paying interest. You have $2K in an EF -- that is sufficient as a bare-bones EF for now. Stop putting money into savings. Stop putting extra at your SLs. Pay the minimums on everything except that CC, and throw all the extra cash you can find at the CC until it is gone. Once you accomplish that, throw everything at the other CC that will start accruing interest in June.
4. What are the rates on your student loans? If they are low enough and tax-deductible, you may not want to prepay them, as you would likely do better in the market.
5. Do you have a 401(k) with a match at work? If so, as soon as you are out of the immediate CC debt, do whatever you need to do to get the match.
6. Second the notion to pick up a side hustle, even if it's just some seasonal work. Your rent is a pretty high percentage of your take-home income, and when you add your loans/debt payment back in, you're always going to feel tight -- you're really not throwing money at stupid stuff at all, but when your fixed expenses are that comparatively high, you just don't have a lot to work with. You need to knock out at least the CCs (and maybe the SLs, depending on the rates) to give yourself some breathing room -- just the CC payments look to be over 10% of you take-home, so knocking those out will feel very good and allow you to start saving for some longer-term needs (like car repairs/replacement, retirement, larger EF, etc.).
