Dp has been suffering from stress for a while - it's a general feeling of tension and edginess rather than in response to work or anything else specific (he's doing a job that he's good at and that is only occasionally stressful in itself). He suffers physical problems sometimes (backache, knee pain etc) and describes his head 'feeling funny' - he's seen the gp a few times, who hasn't found any physical problems, and has been sent on a stress management course by them which he didn't really find helpful. He goes to the gym regularly.
I'm getting frustrated though, if I'm completely honest - I'm pregnant, knackered from looking after a very lively 2.5yr old and doing all the housework, DIY, gardening etc (he's always too tired/tense), and though I know he is suffering from poor sleep, so am I at the moment. He is trying to help himself through meditation and yoga, but even that I get irritated by - eg by him declaring he needs to relax on a weekend afternoon and shutting himself in the lounge with the curtains drawn. I've been giving him massages and really trying to be understanding and patient, but sometimes just feel so frustrated and taken for granted. I feel like it is affecting our relationship.
We have dc2 due in a couple of months and I know this is going to make him feel more stressed, but also that I'm going to need more support from him. Can anyone who has felt similar, or whose dp has felt similar, offer any advice on helping him through this more constructively than I am at the moment?
