I've noticed that time & attention does a lot.
If you're used to psychedelics, maybe you remember the first time of trying a new drug. You're really open and curious about what you will encounter. "hey, my body is doing this, interesting. Hey, my mind is doing that, my feelings this, why would that be?".
Try that same mindset and time/space/attention with your regular emotions. So just sit down and feel, be curious. Feel everything and let it be..
Basically:
Time / attention > Room for feeling stuff
More time & attention > embracing those feels > diving into them to see what comes
Surrendering to whatever comes.
Apart from this. It can be that something is blocking you. So you possibly have some unresolved stuff to work through? If that sounds right, maybe try to start cleaning that up and surrender may come?
Best of luck!
