Has my anxiety gotten bad?

Ok so I was diagnosed with depression and anxiety when I was younger about 14 due to personal reasons and harming myself/trying to kill myself.

It was bad at that point but then it got better like I started smoking cannabis and I know I’m gonna seem like the “bad mom” but smoking actually helped and calmed me down especially when I felt like killing myself and I wasn’t so depressed or anxious 24/7

However I’m 21 now, a mother of a one year old beautiful little boy❤️been raped when I was 18, had been in a sort of abusive relationship in the past.

It’s only been the past few weeks my anxiety has been through the roof, was in hospital for relapsing and cutting myself as everything got on top of me, I feel alert all the time and my brain is going 100mph about my ex partner, about things that could happen in general life not specifically do with him but aren’t most likely going to happen, I feel tense like I’ve done something wrong or that something is about to happen.

*im not addicted to cannabis I’m not a bad mom and I use it to treat my depression and my anxiety as the medication they gave me was making me worse*
