I hit my head with my car door two days ago, am I psyching myself out?

Two days ago, I went to take the trash out of my car—as I opened the door I didn’t realize i was directly in front of it. Well the door cracked my right in my forehead right above my eyebrow. I immediately bent over and put my head down for a few seconds cause it hurt so bad. I walked around for the rest of the day with a huge knot on my forehead—it had a little blood but nothing serious just broke the skin. Well I have see the knot go down mostly but it’s still there with a barely noticeable bruise. I got a headache last night and it feels like a lot of pressure in my head. Also feels like the side of my upper head around my temple is swollen very slightly. I keep getting random head pain and the knot is still sensitive—do you think this could develop into something serious? I’m trying not to be a hypochondriac but I’ve been reading about brain injuries, hemorrhages, and hematoma...needless to say I’m scared to death lol. But I don’t have the money to go to the doctors so I really won’t ever know if it’s serious.

It's not uncommon for there to be a knot/bump when you hit your forehead and for pain/tenderness to continue for a few days. There isn't much in the way of deep muscle between your skin and the skull, so there isn't much room for swelling, hence the knot.
A headache is also not uncommon. ICE can help reduce the swelling and ease the tenderness.
If the headaches  continue or worsen, you can go to urgent care just to reassure yourself.
