Sensory overload/ BPD

[swingsandroundaboutsagain]

Think this is my first thread I've created, just needed a kind of outlet at the moment.
Sorry if it's a long post and a bit jumbled.

I've got BPD, I've done a year of weekly DBT for it and currently doing bi-weekly MBT sessions that is for 18 months.

Routine is key for me I think and obviously it is for children, really struggling with the changes in routine at the moment, like so many others are. I was just about keeping my head above water when I had my weekly therapy sessions and my DS had nursery.
I have a range of anxiety/ BPD related symptoms but the one I struggle with most is having a sensory overload, I'm very sensitive to auditory and physical stimuli and I've realised that I'm quite an introvert and need time to my self to organise my thoughts/ regroup.

I know a lot of things in theory but its just so difficult putting it in to practise. My DS is so active and craves attention. He spends equal time with me and his dad.
My therapist has put me forward for doing an autism assessment but obviously that's on hold at the moment.
I feel like if I were a toy, I'd be one of the broken ones, the defunct ones that are tossed aside. I can't cope in this world and it isn't fair on my DS. I shouldn't be struggling so much with normal average things like socialising/ shopping etc. I love him so much and do really enjoy spending time with him but I just feel so overwhelmed a lot, with this world including him. I do stimulating, fun, encouraging things with him but it isn't fair that my limit is reached easily and I'm not spending as much quality time with him as I'd like.
I can connect and resonate with my friends at therapy on various issues, but none of them have children. Just wanted to see if theres anyone struggling with sensory issues when being a parent?

Yes Op very much so, I think there's lots of people who feel the same! (You might well get more replies if this were posted in the Chat section)
Sometimes my head is just spinning from listening even for a few minutes to my DD talking but I want her to feel loved and listened too so I breathe in and out slowly and have small breaks by going to the kitchen and putting the kettle on or going to the bathroom.
It's very common to feel 'touched out' and over talked to, I get motion sickness when my DD spins around when playing. I find being a parent is exhausting mentally and physically especially if you are managing by yourself.
I also struggled with socialising and shopping, you're really not alone with that!
I don't have friends now, it became all too much to cope with.
You sound like a very caring, loving mum -little and often time to yourself in another room allows you to recover and regain energy.
The old saying 'it takes a village to raise a child' and here we are doing alone!
Be kind to yourself, acknowledge what you need too as a person and you'll work out what's best for both of you.
