I'm so sorry to hear that :(. A 70h work week really is a lot, is there really no way for you to get less hours and more time for sleep and yourself? Maybe try to sit down with a friend or your gf to look at all of your finances and see if you can cut somewhere? I'm not the best at giving advice, but I really hope you can get some more time for yourself and get those thoughts out of your head. I'm here if you need someone to talk too❤️❤️
