I am sorry you are feeling this way.
Perhaps reach out to your Dr for mental health support and therapy? Look up the attachment theories formed in childhood, that have a long lasting negative impact in your life. Just to see if there’s anything there that you relate to.
Including trauma responses… it sounds like you may be having the ‘fawning’ response, it’s a self protection which became built in to protect you in childhood and youth, that have unhelpfully continued into your adult years. Like constantly people pleasing - to the detriment of yourself. All that low self esteem, self hate, shame, self blame and doubts. Lacking confidence to speak authentically, scared of being judged, or rejected.
There is help out there, to help you cope, and try to change the way you see things for the better, and actively trying to change your behaviour and self esteem problems. Learning how to think positively about yourself, rather than ruminating on the negatives.
Also look into, is a rarer and often undiagnosed or misdiagnosed subtype of Borderline personality disorder. It is called ‘Quiet Borderline’ or ‘high functioning borderline’.
The people pleasing, fear of rejection, loss of self and lack of an identity, the negative talk and self blame and acting in on yourself, as opposed to outbursts. These are just some of the signs & symptoms.
I am not a medical expert, but have read a lot on psychology and trauma, and so have a limited but reasonable understanding of what it could be, it may be that you look into all of this and feel it does not apply, but it’s a place to start in the meantime, and perhaps reflect and recognise why you do what you do, and feel how you feel. I am sure there are answers to those questions that only a medical professional could help with.
It doesn’t sound like a temporary feeling, the way you have described it being life long, and what you ‘always’ feel your can never say or do. Be gentle with yourself, we can often be our own worst enemies at times. Remember that you have worth, you are are valued, loved, and have so much to be happy about with your precious child, and all the love, and adventures you have ahead of you as a Mum. Cherish
the good moments, and try writing out all the positives about you, your life, and the world. 💐
