The same thing happened to me eary in my campaign,running out of resources every hr,and no doubt others have had the same problem.I think the best thing to do in this scenario is first,CARRY on playing,dont restart as its more realistic if you keep plugging away and learning from it,secondly shut EVERYTHING down,research,manufacture and each and every track.Then get some paper out and a pencil and try and draw up some sort of basic strategy that you will try to adhere to in your game.For instance,what is your MAIN priority early on?answer is ALWAYS protection,the ability to protect your soldiers,and that means armour.So make sure you are churning as much armour out as you possibly can,or you may not even have the resources to build even ONE suit.In your position take 5 minutes.Look around the map and establish where most of your most valuable resources appear to be,in my game the Balkans are VERY high in high grade materials,so naturally they must stay active if at all possible,and it needs to be connected to my INITIAL (Stuttgart) base.Also,consider trying to expand even more to try and relieve the defecit,you never know a few more provinces(if they are part of your countrys' capital)could be there for the taking.Also remember you can BARTER for resources,for example,if you are mining loads of cheap materials you can trade these to the Cyborgs for high grade materials,and the same can be said for the Psionics too,who happen to be in the good books with me and the Cyborgs hate me!...so far.With this trading taking place you can help yourself,and of course each other.
I TOTALLY recommend trying to capture the 'ports',or the areas with thin blue lines trailing from them as these indicate sea routes,and are PERFECT additions to your track system,as you can cut through swathes of territory with just ONE track!for example,Spain links up directly with Istanbul in the East,which means you can link these 2 up with just one track,saving you loads of track that would otherwise have gone through much of Europe.I had a problem in my game as the Cultists had held this territory for much of the game and so I needed to invade them many times to capture this port.Believe me,it was worth it.
Another problem is expansion too,you can expand too fast or too slow,I believe a balance should SOMEHOW be struck.Grow too fast and you can lose all sense of direction and probably lose all your resources too as you drive your 'Blitzkrieg' through the territories.Go too slow and you risk the Cultists taking those precious lands for themselves,putting you in a real danger early on.
Concentrate on securing mainland Europe and then stop,get your technology on the rise,and when you feel safer in the field attack the other territories and grab their lands,dont forget to compensate them for your unwanted aggression
.Believe me,dont hang around til they ask for your help,go in and grab it by force,you NEED these lands.If you manage to relieve their suffering my compensating them with many resources they will eventually see it was the right thing to do.You can be waiting a long long time before they ask for your intervening,that simply is not good enough for me.
Good planning,is the key.If all else fails,then start again,with the knowledge you have already gained,hopefully you should have more success next time.
Let me know if this helped,and if anything needs clarifying more.
Dont forget,the Roman Empire burned itself out in the end due to greed and corruption,they were then easy prey for the barbarians all around them.
