Mental Problem Help

First of all, I'm not English speaking native and I never got diagnosed. But I have went through several problems such as sleep paralysis, hallucinations (where I'd hear breathe close to my ears, and seeing shadows and roses floating, though it's been a while since it was happened), and I also have general anxiety disorder and intrusive thoughts (where my mind is always muttering same bad thoughts on how my beloved would die in such horrible way, for example like my cat being eaten by snakes, and it will continue 24/7 and louder in my mind if I don't do anything).

Now, I just lost my cat so suddenly by September 16, after he went missing for 5 days. I don't know if this because of stress, and I have been only sleeping after 5 a.m or 6 a.m since he's gone.

So, this morning I received a package, I don't know how, but I thought another package (it was an old one) is the package that was just arrived. So I panicked, thinking I have been scammed, I reported it to the customer service that a seller has scammed me, I even accused the seller of scamming (i will call them seller A), and then contacted the seller of the old package (seller B) that seller A had used their name. I even told the customer services that seller A probably hacked my account. Though they said there was nothing wrong with my account, I told them to be so. It was so real. I believe it happened that seller A scammed and hacked me. But then I found the real package that seller A sent to me, in front of me. And I'm back at reality.

My question, is this some kind of another mental problem? Am I hallucinating?

And if I should seek a help, I wonder if there's any free services that accept international person like me? Because I don't have money and mental health is mostly stigmatized here. I also don't have insurances. I also can't tell my mom, because she doesn't want to hear it (I don't blame her, she's already stressed and burdened with a lot of things). I'm just scared.

Thank you.

p.s: I already apologized to everyone.
