it's hard to say whether or not the problems you solve should take less than 2-5 hours, but two pieces of advice:
1. in an interview, whether you solve the problem is less important than demonstrating how you approach solving problems. think about it like being asked to find a needle in a haystack.
2. don't think you have to score a job at a Google right out of school. there are lots of opportunities in less stressful environments.
ok I lied, I have more advice...
3. as an alternative, write good quality useful software
and post it to a hit repos, go answer questions on stack overflow, demonstrate your knowledge and abilities. become an expert in some area that interests you.
4. maybe you don't want to be a programmer. that's ok. your background will still give you an edge. I have a colleague that worked for a couple years as programmer and ditched it for PhD program in neuroscience (not thAt that is any less stressful).
5. consider getting professional career advice and coaching.
6. consider getting help for your anxiety. worrying whether your smart enough or how hard the problem is will keep you from actually problem solving.
