Try your hardest to keep positive. There is a reason for your difficult situations. Don’t be afraid to ask for help before you get to breaking point e.g tell the schools of your difficulty help from Tomchei Shabbos etc. Sometimes it pays to offer your servicesas a volunteer. – Even if the person cant take you they may know somone who can. Also pays to make yourself available on a temporary basis.
