Try going back down the AD route through your GP.
All medications have side effects. My experience of this type of drug is that there is an initial period where you will feel off, push through this period and hopefully then there will be a period of calm and you can gradually integrate yourself back into normal life.
Be prepared for the drugs to be a long road, certainly no quick fix. A couple of people close to me took Citalopram for anxiety/mild depression and were on the drug for several years. A GP told me a very general rule of thumb is that you need to stay on the medication for at least as long as you have been feeling ill, sometimes a lot longer.
Then perhaps ask for cognitive behavioural therapy, the NHS provide this although there is a waiting list of a couple months (but by then the medication should be helping).
I have no experience of hypnotherapy so wouldn't feel comfortable offering an opinion, some say it works....
Best of luck, you are not alone
