Is it normal the emotions i'm having?
This is going to be long but please I need some sort or advice or something, realistically I'll take anything..
Now the last 6-7 months for reasons i dont know, I've been having a lot of emotional problems that I dont know if they're normal or something more like a mental disorder. I graduated highschool back in june and in september I started my first semester of univeristy, I didn't take the transition well cause I lost contact with a majority of people that I used to see in school and I haven't made a single new friend in uni.
On top of being alone all the time now, I struggled in all my university classes and failed two of them altogether, realistically I don't know why I'm wasting money in university when I dont even know what I want to do for a living.. but anyways I went cause everyone else was and the pressures that we're coming from my family.
Now my family is a whole other reason why I can't deal with things right now. Im 18 years old and I just found out about 5 months ago that my mom was pregnant and that I am having a baby sister. Being an only child, I've wanted something like this my whole life.. but now im having second thoughts. I don't want to believe this is typical sibling jealousy but I have a fear that my parents are just going to "forget about me" I mean, im an adult now who's expected to move out in the next few years and they'll be raising a whole new child.. it makes me feel like they are starting a brand new life, ome that doesn't include me because of the age difference. Man im crying right now just typing this.
It just feels like there's been a lot of big changes going on in my life and it is really overwhelming. I have lots of crying apells now and I argue more than ever with everyone especially my parents. I cry so easily when I even try to talk about how I feel. I have panic atracks alot now. I also have anxiety which has gotten much worse recently. I skipped a lot of school last semester, which probably was the cause for me failing but I felt like I didn't know what I was doing so what was the point I going. Sadly, I self harmed when i had one of my panic attacks which ended me up in the hospital being treated for a concussion which no one knows about because I told everyone I fell. And I just have a lot of sleepless nights, most of them im up till craxy hours crying sometimes for what feels like no particular reason.
There is a lot more that I left put because I couldn't type forever but these are just some key points. Please help me in some way.
