Stress can make sleeping hard. I get that way alot myself. Good luck finding apartment. That alone is stressful task! Are you seeking any treatment to help or have any type of support? Hang in there.

No there isn't much available as far as therapy goes. Not sleeping definitely makes your mindset far worse. The only thing I have right now is prayer, I'm not a religious fanatic but it does help a little.

There must be therapy available somewhere. Keep looking mate. In the meantime we are here for you

There's not much I feel qualified to offer except my usual: Take care of your body and your mind tends to follow. If you're not sleeping, then your body needs to be worked harder ( it's a simple formula ). Very few people who work themselves at a physically demanding level for long enough won't sleep.

Also try to eat well, and not eat too much or too close to bedtime, and if you take supplements, take them mostly before lunch with meals. If you don't take supplements, a good multivitamin isn't going to do you any harm.

On the loneliness factor. That's rough on a lot of us, and the pandemic management isn't helping. One thing you might try that could help on all accounts, is to volunteer time at your local food bank, or with a group like habitat for humanity. They'll get you doing something physical while you are interacting with people. Who knows, maybe you'll meet some new friends, maybe even a romantic interest.

You are stronger than you know. Believe it! Keep moving forward, and things will improve.

You have to believe in yourself, and work on the relationships with family. They care about you, if your family didnt care about you, they would tell you to move out. Love your family unconditionally.
