Advise, ESA, PIP what can I claim

Hi all hoping for some advice

I’m currently self Employed and have been for 10+ years
My partner does not work due to disability she receives PIP enhanced daily and Mob
We have 4 Children and we currently receive Working Tax Credits

Unfortunately I’ve fell on some bad health myself
I’m suffering with Gout, a dislocated Sholder and my mental health is so bad I’ve been told I’m suffering from burnout and I’ve surpassed stage 5 I don’t really understand it all but I just know I’m not well at the moment, I’m not good at all I won’t go into all details but I need some time off work I don’t want to not work i just need some time 2-3 months to try and get better I’ll never recover if I don’t take time too

So my question is obviously being self employed if I don’t work I don’t get paid I know I’ll get the Working tax credit but I can’t afford to live off just that can I claim esa and working tax credits for a few months?

I have checked my NI and I do have few gaps in it last year was a full year but prev to that I have few gaps

I have applied for PIP 4 weeks ago heard nothing yet (i know can take ages) in hope I’ll get it as I do need lot of help from people at the moment doing anything and everything I feel like burden to be honest but all I want to do is get better I just need a little help doing so

Any advise much appreciated
