Losing someone has definitely had a negative effect on my mood, health and productivity. I'm approaching 50 and single and it constantly preys on my mind, often causing issues with relaxing and sleeping well. This obviously means I don't bring "my best self" to work. Of course, having a partner does introduce other responsibilities and pressures, but I'd much prefer having those challenges than the existential dread of living alone. It all comes back to Maslow's Hierarchy of Needs, I suppose. Deficiencies there mean you're not truly fulfilling your potential. Yes, I do recognise how fortunate I am to have food, shelter and some savings, but being alone is still hard to cope with. I hope it's some comfort to know that there are others in the same situation, minroot, and I'm sorry I can't provide any advice other than to keep trying your best and accept that it is enough.
