Hiya,
Having read what you’ve written, as someone else has suggested I would recommend seing a Counsellor. As i am a Counsellor, therapy can be brilliant to get over phobias. What I suggest for the mean time is when thinking about or taking tablets, to tell yourself your going to be ok. Use positive affirmations as much as you can. This will help in the short term but for long term, seeing a Counsellor is the best option. Although therapy doesn’t work for everyone, i guess there’s no harm in trying.
Hope this helps
Kay
