Sorry to hear about the hard times you are experiencing. Like the others said, during tough times you have to dig deep within and find the resolve to pick yourself up, dust yourself off, and take another swing at it! You are not alone though you likely feel like it. Each of us (unless by some freak chance) face dark and challenging times and issues in our life, certainly different from one person to the next. Regardless the issue, for the one slogging through the crap, it is a dark time. Hard times, while never fun, depending on how you react can actually make you a stronger and more confident person better equipped to face the additional obstacles that you, like everyone else will no doubt face again at some point in your future.
Your grit, drive, and stubbornness to overcome your adversity has to come from within. To bolster that, some pray, others meditate, while others reach out to a support network of friends and family. Don't hesitate to reach out to others and employ whatever means needed to strengthen you in your fight to restore your situation to one that is more normal for you.
If discussion with others on this site or venting to this group helps you, then please continue these discussions. I know that this group will certainly offer all the help, comfort, advice and support as we can.
