Just introducing myself

Hello fellas just thought I'd take a chance and hop on this reddit thread and spill my guts a bit. I'm 35 soon to be 36 in 3 months and I slowly been realizing that I might not have it all together in my head 🤣. Life has brought some recent changes to my door step and it made me take a second look at myself in order to reevaluate somethings even though I kept telling myself I'm to old to make a change another part of me kept screaming stop saying that and just do it. Got a new place in a way better neighborhood so when my 3 sons visit me it feels a lot safer started a new relationship that is going really great (sometimes it feels like it's going TOO good) I love this woman deeply and I'm working 2 jobs that I've exeled at. Even with all that something feels off something feels missing. I thought it was the fact that as I get older I'm not as spry and fiery as I used to be then I thought it was the expectations I pile on my self as a man and worrying if I'm meeting up to them or not but honestly I have no idea hell it could a mix of all that. I'm hoping any of you fellas who may have gone through or are going through the same thing can help. Thank you in advance.
