Could I have (D)PD?

Hi everyone,
lately due to some occuring events I have done a lot of thinking about myself and tryinng to figure out what is going on.. I think I might have DPD or maybe some other PD but I am not sure. Here are some characteristics about me that make me suspect something is 'wrong':

-I always need attention; good or bad (although I am shy and don't like being the centre of attention in groups)
- When I am in a relationship I need constant validation that everything is fine. I mean literally every hour.. When I don't hear from my partner for a couple of hours I am convinced he is thinking of leaving me and I get very anxious, then when I hear from him I am on top of the world. When I don't hear from him I start feeling depressed very easily and will do anything to get his attention (sending sexy texts, pics, try calling him, anything to get a reaction and see things are still good). I get veryyy clingy and I know this scares people off but I can't help/control it. If he doesn't respond instantly I will check his social media to see if he was active/ignoring me. I feel like a stalker.
- I get depressed a lot, fantasize about suicide but have no intention yet of actually doing it, I used to self harm when I was younger, sometimes still think about it though
- Sometimes I feel nothing/no empathy but other times it seems like everything I didn't feel before comes rushing in at once and overwhelmes me.
- I feel like I am addicted to drama/creating drama and for some reason need feeling anxious/hurt. When I am in a stable relationship and get all the attention I need, I feel bored and try to create drama in order for me to feel better and worse at the same time.

I recently dated someone with NPD and this got me to my lowest point ever cause I totally lost control and feel like I needed him so bad and all he did was ignore me when I got clingy, it got so bad I started cutting myself again after 8 years of not doing it.

Some stats: female, 28 y/o, relatively normal childhood although my parents divorced when I was 6.

Thanks for any insights!!

Yes you can.

But should you self diagnose in this way?
No.

Could it be something else?
Yes.

Can anyone on this forum give you a diagnosis?
No.

Besides, how do you know your ex was a narcissist?

I know exactly how you feel, and have many friends (myself included) who have been through the same thing. I know, for the sake of anonymity we tend to not offer any true sense f community or connection, but.. If you ever want to talk, I'm here. It gets better when you have people who understand. *mod edit*
