Do i need help ?

hello.I'm a 19 year old male. For the past year all I want to do is be on my own.
I used hang out with friends, talk to other people. But, i don't want it anymore.
Now, i hate being in large groups and introducing myself.
And when i'm alone, i always be so sad, unhappy and usually i can't sleep.
I started to hate myself, because i'm not good in anything, i don't have too much friends or a girlfriend.
I just feel good two days in a week, and the rest I stay alone in my room.
I don't miss a good conversation or someone's presence.

I never talked about this with anyone.
Sometimes i want do, but i'm not sure, i'm afraid to have a conversation about my feelings.

In this moment I`m really confused, do i have BPD ? do i have seek a therapist?

If i posted this in wrong forum, i apologize.

Hi enough, it sounds like you are going through something very hard though I really can't say what. It doesn’t sound so much like BPD but it could be and it could be many other issues.
If you have the option of seeing a counselor or therapist I suggest you do. I also would suggest you try exploring a bit more in depth what triggered you to feel this way because it certainly didn’t come out of nowhere.

You don't have to worry about posting stuff in "the wrong" forum but you might want to try posting in some of the more general forums as well because what you describe could be the result of many things.

Thank you ShakyCore, today searching about my case, i saw about dysthymia and i think i have.
Reading the symptoms, i have 90% of them. So i decided seek a psychologist, i really want discover what i have and do the right things to get a better life.
Thank you again.
