Thanks arnicangel. My boss is leaving in a month and hasn't been great but more from an inexperienced/busy way than actually being deliberately obtuse. The last call I had was basically all about getting something in place that would be supportive and that I would be doing fresh work. I was genuinely in a decent place and whilst not excited to be going back, feeling okay and pretty positive. Then he threw in the curveball that saying the work that I have worried, stressed and which contributed to me being off hasn't been touched and whilst it would be allocated to my colleague, i'd be helping. That work and where it is at is the root of the guilt and negativity I was having and I had 6 counselling sessions that basically got into me understanding that I was ill and not my usual self etc. I've worked for 38 years and always had positive reviews etc. so I shouldn't feel guilty about it and it's not my problem to solve.
That issue really knocked me back and whilst I'm not scared of the GP call per se (previous calls have always been good), rationality doesn't always feature in anything and I'm quite angry to be in the position I am now in after all the work with counselling etc. I wanted to speak to Occ Health about it so they would put it straight rather than me, but here we are weeks later and i've not been able to speak to anyone.
I'm not on any medication and you are right, i'm not currently in a good position to be back. However, I need my salary to continue and I only have 6 weeks or so left of that. Boss mentioned in his last email that I have Group Income Protection but I really don't have any clue about what the policy is and don't feel like I'd qualify. I have no access to any company systems at the moment as my login stuff has all expired.
I didn't find occ health particularly useful last time. I felt she just wanted me to go on medication and then I'd be fine to return in a couple of weeks and was basically wanting to force me into calls with work that I just wasn't ready for them and I really didn't feel much support at all. Her report was ok though. I'm hoping I might get someone else this time.
Current problem is more that I feel constantly anxious on edge and I'd really gotten over being like that months ago, maybe I do need medication? Anyway, nice early start for me in the morning to call GP. Thanks for your help and kind words.
