@Elkhart very sorry about your situation.
Agree with
@LetItSnow about surrounding yourself with loved ones and good friends. Most people know what it feels like to feel intensely discouraged. It's okay to let others be supportive of you. They care about you. Someday, they may be feeling discouraged themselves, and you'll be there for them. Just saying.
Here are some practical suggestions concerning your lease (I'm not providing any legal advice; just thinking out loud):
1. Make prompt arrangements to discuss this situation with your lessor/landlord as soon as possible.
2. Be honest and polite when describing your situation to the landlord - especially since you already have a positive lease payment record with the landlord. If you and the landlord can reach a mutually-acceptable agreement, you may be able to save some money by ending your lease early and/or not have your credit score dinged for non-payment of the lease. It is likely your landlord does not want to go through the time-consuming and costly hassle of suing you for non-payment of the lease because you can't tender the lease payments anyway due to your present financial situation.
3. Is there is an "early termination clause" in your lease agreement? If yes, review it carefully. Your situation sounds similar to loss of a job (i.e., lessee encounters a financial hardship due to sudden loss of employment, and as a direct result of the hardship, lessee no longer has income to pay lease). In some lease agreements, a financial hardship may provide an "out" from the lease, although you may still have to pay some type of fee to the landlord, or whatever.
4. You might also want to determine if your landlord is required to mitigate damages in your state. If yes, then the landlord may be under a duty to make a reasonable effort to re-lease the flat (and relieve you of some or all of the remaining lease payments). You'll have to review your state laws about this topic.
It's useful to take some time and do some realistic thinking: formulate a Plan B and a Plan C.
Write it down ... organize your thoughts ... and identify your "must haves" at this time. Then, begin to move forward and regroup, using various resources available to you (e.g., job networks, loan repayment counseling, career counseling, personal counseling, etc.). Please know I realize you're feeling discouraged at this time and I'm not diminishing how you're feeling right now. I understand.
Above all else ... I wish you well and hope things begin to turn around for you.
