I just need someone to talk too

I am an overthinker so something can haunt me for months,I tend to think I'm overthinking or being dramatic so I just bury it

I'm in my first relationship and obviously I want it to be my last

There's just been things that have happened ik out of good intention that have led me to feeling hurt,the thing is I have no one to talk too about it so I feel like I'm drowning and always questioning if how I feel is valid, I don't want to bring something up cuz that's hard in the first place but also if it's just something stupid then it's something I can solve on my own then bringing it to him I don't want to make a post of what's bothering me I'm doing this so I can reach out
