HUGE TYPO UP THERE
If it gets WORSE, go see a psychologist. I didn't mean to say better, haha.
If what I said helps you and you get better, you're straight. You just kind of needed a wake-up call to tell you that those delusional thoughts are ********, and they are completely possible to the most sanest people on Earth, so you're not alone.
Who would honestly try to come and inject you with HIV/AIDS? I have never heard of that happening in the history of AIDS since the 80s. People aren't out to get you, everyone goes about their own life, they care about themselves too much. Now, the whole thing about you giving aids to someone. You don't even have HIV/AIDS, and if it makes you feel better go get tested for it. Take your thoughts one step at a time. You need to lose weight to get a girlfriend? Lose the weight, THEN worry about getting a girlfriend, once you have a girlfriend, go both get tested for any STD's.
You're being really paranoid. Start questioning ANY NEGATIVE THOUGHTS. Like the ones you have listed, negative thoughts only bring you down, and they are ALL delusional.
If it never gets better go see a psychologist, could be anxiety problems, OCD, or paranoid schizophrenia. Don't get paranoid about what mental health problems you may have either, this does not help with anxiety. You have no mental health problems right now because you haven't been officially diagnosed.
I hope this has helped.
or someone anywhere came in the apartment do note thats a typo
