Yes...do you have family you can fall back on in your home country to give emergency help for a few days ? Ideally you want to be in your home country to get a new life started.
UK is a much more sympathetic country than Thailand is especially if a child is involved. Within days of arriving in the country you could claim emergency assistance (loan from Universal credit payable same day). If you travel back on your own you are literally On Your Own..so only you as a parent can make a decision but ideas like go fund me usually work if constructed in a certain way....best of luck.
...there's always one (yes you Alan Snowly) who thinks they are being clever...looks like a right dickhead in his photo profile 🤣..I think if he met you he would shit himself 🤣🤣🤣
