Tired of this shit happening again and again.

I have been wanting to go to the doctor since the past week and for that to happen I have to face my social anxiety.
I called the doctor she said she works till 3pm but when I went there on Thursday I knocked on the door no one opened , so I called her again and she told me that she only worked for a half day. What tha fuck is wrong with you like you work however you want without telling your patients??

I called her again today , her assistant told me she works till 2:30pm and when I went there at 12:40 I found no one , I called her again she told me the doctor went to eat lunch and she'll comeback at 1pm , I waited for fucking 40 mins and she didn't comeback.
Wtf being disrespectful and lying to your patients it's not cool nor good.
Doctors in my country have become so fucking lazyyy.

I called another doctor, I asked his assistant if he works today and at what time he finishes, she tried to pick a fight with me by telling me that I should ask her if I can come or not and to not ask her about the time he finishes, I told her no I ask however I want and she still continues with her attitude so I hung up the phone cause I was so fucking done.
And they still ask me why I hate people and why I avoid them. Well this a great example right here.

Man I'm so tired physically and mentally, how can a person live a normal happy life while being treated like a fuking peace of shit.
Like I don't know who to fight now, should I stand up for my toxic parents or toxic people outside or doctors , this is so overwhelming.
I'm trying my best but I only get rudeness and more problems on top of my now problems.😔
