I think I might be able to see myself in some of what you say.
When I hit a life low, I want to get on that sailboat. I actually did that (not a sailboat) once in life.
I decided in a week to quit my job and travel. Alone. That is exactly what it felt like.
I stood on incredibly beautiful mountains and then felt the desire to share the beauty with someone.
I thought that I needed a partner. So some years down the track I have realized that isn't the case.
That can, beauty and happiness in my own moments. That it comes from within, and it isn't dependent on someone else. That took me some years and heart ache to realize. I think I might be a bit slow
I also discovered if you throw life to the wind eventually you have to come back and if nothing within you has changed then life will be exactly the same.
We are not joyous humans all smiles and Instagram stories where everything is perfect.
Without getting into conspiracy theory, media does send subliminal messages, along with governments, politicians and money makers. All saying how we should feel and what success looks like. It's manufactured and people turn themselves inside out trying to fit the mould.
There is a great video on this site which talks about vulnerability.
https://www.youtube.com/watch?v=iCvmsMzlF7oI started to think about allowing yourself to feel strength in vulnerability and own it as such
My flaws I own as work I need to do. Not who I am. Parts of myself that require work. To do that you have to forgive yourself for your mistakes.
Another great tool is CBT. You don't need to follow it like a religion. You can simply take the concept and challenge yourself. Challange negative thinking. Especially if you had a relationship with a person with BPD. You need to ask yourself hard questions and take responsibility for your own actions and part in that relationship.
Moodgym is quite good and free. Ecouch goes into relationships.
It can seem simplistic at first. Some of it didn't relate to me at all but it does allow you sit with your thoughts for a while and just challenge some of the ideas you have. I found that useful.
Especially come out of a relationship with a BPD person and feeling confused, used, disillusioned, lonely and deeply sad.
My objective isn't to turn myself in to a shiny, happy person. My objective is to live my authentic self which is where I see contentment "lives" and strength. Then perhaps you aren't looking for society to validate who you are and resenting "the lie"
The other point I focus on is making choices. Working through the choices I am making and allowing myself to make assessments of those choices, and I find I don't want to continue with a scenario I can simply change it without seeing it as a failure or negative.
I shouldn't really analyze your comments. I don't know you and that would be unfair.
I would like to ask you a question. Do you think you are giving too much power to other factors outside of yourself and maybe making it a focus?
