irrational fear of hell and damnation and spiralling, please help me?
Nothing in what the Buddha taught says that one is not to enjoy righteously earned pleasures. One gives up the world at one's own pace. But the whole world recognizes (if it doesn't practice) the corrupting nature of lies, harm, theft and unrestrained self indulgence. The key idea there is 'righteously earned'. You need to develop a sense of where the line is drawn between activities that create bad kamma and those that create good kamma. One does not go to Hell practicing only good deeds. That is basic training:

Create good kamma: Practice generosity. Find a vihara and make gifts to the bhikkhus.

Avoid bad kamma:

Train yourself to refrain from saying things that are not true.
Train yourself to refrain from activities that cause harm to breathing things.
Trin yourself to refrain from taking things that are not givin to you.

That is 'train yourself'. You are not expected to reach perfect behavior over night, the important thing is the direction you are headed. Your fear is rational; right now you are headed in the wrong direction. You do a 180 by taking the first step. 

If you have a good bank account of good kamma and are cultivating a life that avoids making bad kamma what pleasures come to you can be enjoyed without fear and the bad stuff you have already created or newly create will be experienced in an over-all environment of progress towards the good.

If you want to understand this system more deeply I suggest this over-view, which is based on Ananda's Gradual Course:
