Hi I’m 28 M from UK

I’ve been wondering if I possibly have BPD for a few years on and off but only occasionally have I ever looked it into it and normally just end up thinking “no not me, I just need to stop making bad decisions” or something along those lines 

However when I look into to the 9 traits I can strongly relate to atleast 5/6 of them.

The ones that really hit home are the unstable intense relationships, pretty extreme mood swings, explosive anger (particularly when drunk), Impulsive, self-destructive behaviors (gambling, alcohol, drug use) feelings of emptiness/ depression which leads to me chasing a ‘high’

This has effected my life negatively  through my 20s

Few examples being 

impulsive destructive behaviours for example I have suffered from gambling addiction and cocaine misuse for most of my 20s. Tried to quit both many times but despite knowing the consequences still doing it again eventually 

Ruining relationships through rash on the spot choices (mainly stemming from me making jealous and unfounded accusations) and losing my temper when in reality I have been the one more often than not acting inappropriately around towards other women when in a relationship, especially when under the influence of alcohol and drugs. which in itself fills me with shame. 

I always feel regret and shame shortly after these impulsive tendencies yet still make the same mistakes again and again 

I am looking to make a appointment with my GP this week and discuss this but was just hoping for any advice
