I've been through a lot in the last 6 or so years. I've had therapy, course of ADs and have put it all to bed.
Everything is going right in my life right now, DS is good after some minor health problems and loves school, no drama with XH (his dad) relationship with a very old friend is amazing, we are both committed and want the same things, works going well, have a few good holidays booked. (Not a stealth boast just trying to set the scene)
But, I'm have a sense of doom I can't shake, I'm struggling with everyday things, like panicking about parents evening, hating my own company, worring about running out of money, that I've gained weight, worrying about silly things at work like requesting a rest day and that I've forgotten to do something and they will sack me
worrying DS is getting bullied (never had a problem with this btw) worrying I'm infertile as me and DP planning to start TTC at the beginning of next year. Worrying all my friends hate me, and people don't like me in general; panicking about the future. I have an assesment day at work next week and I physically feel ill about it, like I want to cry/be sick at the same time. I've done about 12 in the past!!!!
It's like I'm a prisoner in my own head ATM. My DM said it could be I'm used to major stress I don't know how to be without it 
I've worked so so so hard to get here and it's taken years and ten tons of shite to deal with and get past I'm just so frustrated with myself and I'm a negative person to be around.
DP is being amazing, bless him but I need to snap out of it.
Has anyone else gone through this?
