Incase you don't find a better solution. Keep yourself clean, this gives you access to hotel lobbies, airports etc. So you can keep varm and get some sleep. Especially in airports(sleep). Seek out food banks for food, salvation army etc.if you live in a country with social services, seek them out to get somewhere to live and money!!

If you have a rucksack with extra set of clothing you can use handicap toilets to wash your spare clothes, drying them won't be as easy during winter time. If you're in a country with laundrymats, try to have some change for drying every now and then. 

Hygiene is important. Looking 'good' or groomed if you will grants you better access to sites other homeless don't have access to and make living easier.

If you live in a state or country where you can recycle bottles for money spend day time to gather such. Best times are early in the morning untill lunch. As well as early night. 

Food can be also found by dumpster diving around bakeries right after closing time, as they normally throw it all in a big bin that protects it from the dirty dumpster. Remember to smell and taste first before eating. 

Also I'm so sorry you have to go through this, we all deserve better. Everyone does. Love yourself, even if it feels like the world doesn't love you. Easier said than done

My biggest mistake was ever thinking anyone(including myself) need to experience suffering to understand heaven. That to experience happiness you need to experience pain. You do deserve better, I deserve better, anyone reading this and not reading this deserves better. Every child deserves love, every child deserves roof over their head, every child deserves food to eat, a place to play, a soulmate, a place to fit inn etc. Be it human, or animal.

Don't ever think you're not needed, this goes for Single letter man, anyone reading this or not reading this. We are ALL needed. 

I truly truly hope some hidden hand leads you to a good warm place, serves you meals to keep you full and happy and to some place you feel you fit in where you can love and be loved <3

Take care of yourself man. And please seek social services if your country has such. And I hope you found any helpful tips in my text
