Dad, I turned 22 today!!

Hey Dad, it's my 22nd birthday and you didn't even bother to wish me.
It's only my mum and my grandparents who made me feel like I exist. Not even the friends I had spent 4 years in my university wished me. They probably forgot too soon.
It's a tough day today. Got rejected from another interview, struggling with technical knowledge, I wish you had guided me. Also, it's hard to accept that hardly anyone wished me this year. My phone was blowing up last year with birthday texts and calls. A lot can change in a year indeed!
All dads here, please give me some nice advice for my 22nd birthday. :)
And, here's a virtual piece of cake for you all.🍰
