I was listening to a podcast on Spotify and this is how they described people with BPD. 

"Being connected and feeling secure" is truly reason of my personal issues that I have had throughout my life. 

I have given away too much from myself to feel connected to others. It probably started within my family since early age. 

Currently I am struggling with my broken relationship with my FP. So from time to time I tell myself that I am feeling bad because my needs for being connected and feeling secure are not met. But it is also wrong to be in a state of mind like that. I am a person on my own and so on... I am able to shake off bad feelings from time to time after having acknowledged my neediness.
