Is it normal for over a year now i go to bed & wake up with a racing heart?

Don't dick around with this. Go to another doctor, not the one that is giving you your prescriptions and tell them this. To me, although the advice given is excellent, it sounds a lot like low blood pressure. You mentioned in an earlier post that you're on blood pressure medication. I think you need the level of medication checked.
I too am on antidepressants and have found the right amount in the right type after a long time of trial and error. They are not all the same. And when on one brand ( I can't remember which) I had the same type of symptoms. In a nutshell it sounds to me like you need your meds quantified by a second opinion.

That's called anxiety and is also the cause of you not being able to sleep well in the first place.

If you can work out what you're so anxious about then you can work out what to do about it.

If you're a heavy smoker, that can interfere with getting to sleep because nicotine is a stimulant, as is coffee if you have too much or any late in the day. If you are a smoker, the anxiety first thing in the morning could well be withdrawals because your brain is low on nicotine.

I have had that too. It was really awful when I didn't take my medications for like six weeks last year, but I did really want to exercise a lot though.
