Wtf…I need advice

Life is weighing heavy on me rn I’ve managed to get to a place where I’m happy with my progress…but I feel like I’ve been hit from so many different angles I can’t figure out what my next move is. My kids dad just came home from a 5 year bid we’ve gotten to a place of agreement and wanting to work towards our goals together…however I’ve been working on my own struggles such as alcoholism and substance abuse…he’s able to indulge in these things and it seems to have no effect on his mental or wellbeing…I’m not able to resist my own urges around him but I’m also aware of my boundaries…however I’ve made it known that I’m struggling and I don’t like the place I’m in right now…I feel like I’m under pressure that I don’t need or want…I have to work today but I don’t want to go because Ive had no sleep but I don’t want to jeopardize my job or how far I’ve come. I’m so frustrated….I do not feel comfortable going to work like this….
