Insomnia??

Does anyone else struggle with this? Idk if that’s what this is but I’m at the point I think I should see a doctor to get sleeping medicine or whatever. I really didnt want to but it’s been 3 months since I’ve been able to sleep normal. It’s 2 AM here and Ive been laying down for hours now with my eyes clothes trying to sleep but I just can’t. This is an every night thing now...

My dad died in June so I don’t know if that’s what has caused this? It started right after that pretty much. I’ve never had issues with sleeping before this 😕 Any advice? I just want to sleep.
