Hi @Catiepiller ,
May I ask what is your line of work? Have you questioned yourself if this is still suitable for you - a career that you are passionate and worthy of pursuing in the long run?
I am sure it's not easy to release the fear. I understand fear can be paralysing as I have had that experience too. But I usually forced myself to get it done by deadline regardless.
Is there any activity that help you relax?
For me, once I get back to a bit of 'achievement', be it in something as simple as getting the house cleaned or cooking a new recipe or creating a new genre of artwork, I can transition to work easier after. But this is just for me, I am sure it will be different for you.
It's worth experimenting what works for you. Try new things or activities each day. You may grow new herbs, go kayaking, have tea party with the kids, etc. Every day will be a tiny bit of achievement and do remember to give yourself a pat at the back after. Hopefully you will feel more confident in tackling your work.
