despise my SIL

Like literally hate her.. I act like a child every time I have to be around her come up with any excuse not to go just can not fucking deal with her... She is on drugs (not talking about just pot)  and my son has no idea who she is cause all she does is bounce around bf to be job to job... My sons 1st birthday is coming up and I really just don't want her there.. Obviously that is not an option so she'll be there.😤 I know I need to act like an adult and just suck it up but I am going to be 37 weeks pregnant at the time and i just don't have the patience for her bullshit... Lol just venting! 👇🏼 this is how I will be handling the situation lol
