Hello fellow Dad's! New to the forum and asking for support if you can help...

Hi Dad's! I'm Jonnie, I'm 40 and have a 2 nearly 3 year old daughter who I love to bits. I've had a few issues with morale, motivation and self purpose and was wondering if anyone else has felt like this? A little bit about me: I'm 40, have several health issues (previous brain tumours, epilepsy and most recently had surgery for colon cancer which I'm currently on chemo tablets for). In my 20's I had loads of friends, always meeting up and going for a drink with people or partying etc but now I have epilepsy I've had to give up the booze and doing certain social things as they're too late and tiring for me now. My massive friend group has slowly drifted off and I can't say I have a real friend I see often anymore for whatever reason. I've had a very varied and unsuccessful career up to now where I work for the NHS. I seem to start a job, not be able to cope and then have to jump ship before being pushed. I feel this has really knocked my confidence and given me lack of motivation in terms of work. We had our daughter during Covid which was not ideal, and probably not the best idea really given my health history which also means most of the parenting burden passes to my wife, which I feel guilty for. She also does a massive amount for me as well so puts huge pressure on her. This has been a very stressful experience for both my wife and I and we often have a tiff about either something I've done or said or something I've not done or said because I don't always think of things she does as it's either not very important to me or due to my health I haven't really thought about it. When our daughter is being lovely she's an angel. However, when she's being a pickle I don't have enough patience with her which causes rifts. I don't know whether it's because of my health or just because I'm in this rut at the moment where I can't be bothered with anything that stresses me. I'm really just looking to see if anyone else has experienced what/some of what I'm going through and/or can give advice or moral support that would be much appreciated. Apologies for the mass amount of text 🙂
