Drambling
You have a lot of water/fire in your chart, which may be somewhat dramatic in its emotional expression and style. There things are always going to need some lind of a creative outlet, along with the opportunity to really bond with other people on an emoionally meaningful level.
I would not have automatically assumed you might have BPD from looking at your chart, or 'have' anything for that matter. I do see challenges presented by your birthchart that may need to be worked through so that you can express some of the more potentially volatile energies in your chart, at more integrated levels. Perhaps currently, there is a lot of anxiety around you because of unsettling experiences to date, that may make it difficult for you to contain strong feelings.
I see, for example, you have a Saturn/Uranus on the Midheaven square a 1st-House Mars. This might mean that there has been some kind of an early loss, along with early exposure to angry and highly unpredictable behaviour, from a significant care-giver - you may likewise, now find it difficult to handle anger and frustration yourself - visibly, possibly, because of your 1st-House Mars. Then, you have Moon square Pluto, which may again denote early experiences of loss of significant caregivers, which may be something that has left its mark with you now.
Moon square Pluto may denote someone who struggles a great deal with extremes of emotion, once these are triggered. Somehow, there may be the need to get more of a sense that you can survive, even through perceived loss of significant others.
Finally I see that Neptune your chart ruler, opposes Mercury, so there could be an element of escapism in how you interpret the world.
Have you read Donna Cunningham's book, Healing Pluto Problems? I believe it discusses issues such as these, as well as suggesting flower remedies that may help you with developing more of an emotional equilibrium.
Just suggestions.
