When does life get easier?

When does life get easier? It feels like I am drowning. This year I've had to deal with the ex going stupid because he got himself a girlfriend and that was more important than spending time with his kids. Then because he was being so difficult there has been mediators and lawyers involved only for him to turn around after a new lot of arrangements were agreed to that he wasn't happy with them after all and he wouldn't be signing them now. When I wouldn't agree to his new and unreasonable demands he decided to make up a load of lies and place a complaint to child protection which led to me having to deal with them for months only for them to turn around and say there was no substance to the allegations and they were closing the file. Well thanks for that, that was months of stress for nothing! In the middle of all this, my youngest is getting harder and harder to deal with. The tantrums/meltdowns and anger outbursts keep getting worse and my oldest gets more and more sensitive to everything. They constantly fight and won't listen to me. Don't get me wrong when they listen they are amazing, caring, loving kids but that goes out the window so fast when they are having a bad day. I had it suggested that my youngest might be asd so I get the testing done and what do you know yep they are! Well that explains a lot! During the testing process I come to the realisation that there is a good chance my oldest is too but I only just managed to scrape up enough to get the youngest tested and their father won't help he only does the bare minimum though he likes to have everyone believing that he goes above and beyond so I am going to have to wait out the public waiting list for the other child. Thought I might actually be starting to get ahead the kids are a little easier to deal with post-diagnosis, I started back at uni and was really getting into the unit, had an extra pay so was able to do some Christmas shopping and thought awesome I can put a little bit of money away for the holidays. Well while driving my youngest to soccer on Monday the damn car stalls and won't start. I'm stuck at the lights it is stinking hot and all anyone wants to do is abuse the chick stopped at the lights because her damn car won't start. Well 4 hours later I finally get home with the car on the back of a tow truck with that little bit of extra money handed over to the tow truck driver and a car with a broken timing belt. So here I am in tears again no car and its 5 weeks until Christmas. Seriously how much do I have to deal with before life will give me a break! I really struggle with anxiety and depression and suffer from chronic fatigue. These things just make it so hard to deal with life when everything is going smoothly let alone when it isn't. I just want a break, surely nothing else could happen and life will start getting easier right? Not sure what I am asking, think I just needed to vent and to know I'm not the only one life is being an arse too! I think I need a do over
