BPD + Starting Spiritual Journey with Insecurities

NextGEN Medium Vlog takes a look at a question from r/spirituality. The OP has incredible insecurities along with a diagnosis of Borderline Personality Disorder. *NOTE* I didn't look closely enough and specified this video towards Bipolar disorder. The same message is the same, however. Here's my advice for anyone who can't forgive themselves of their mental disorders and want to venture into spirituality and their soul abilities. Here's what the OP posted but has since deleted:

Starting my journey: how do I let go of insecurity?

Hello everyone! Long time lurker here. I (f20) have to admit I am quite nervous to post, yet I am in desperate need of advice/tips/guidance. I started to get into spirituality two years ago. I've been diagnosed with bpd, and since then everything went downhill. I have not many friends or family members, and the ones I do have in my life are extremely toxic. I do have a fear of letting them go, and for some reason I just can't respect myself enough; I don't want to be alone. I have an extreme insecurity when it comes to the amount of people I have in my life (I was thought to think that way as a kid), and this reflects on my quality of living. I hold back from a lot of things, and I want to change it. I put all the blame on myself for not being good enough, or being a terrible person in general. How do I change this mindset with the help of my spirituality? I know therapy is supposed to help, but what else can I do? Now, I've been doing meditation and it helps me realize a lot of stuff. Are there any other things I can try? I would love to know. I just want to find my inner peace and confidence. I hope you have a great day
