Anxiety & feeling guilty about taking medication

Hi everyone

To be honest i'm not sure what the point of this post is, maybe to vent?

I suffer from severe GAD, Hypochondria & possible OCD and have done so for about a year, it was slowly getting worse and I was convinced I was dying all the time, every second of everyday I was anxious and was worried that I was dying of some unknown health condition, this health condition ranged from cancer, strokes, heart attacks, blood clots in my neck name a medical condition I thought I had it. I also cant drive I have my L's because i'm to scared to drive in case I hurt myself or someone else, i also am real anxious if i'm in the car and someone else is driving (especially my grandpa who i'm worried will have a heart attack or stroke behind the wheel) I also have a ritual I perform nightly surrounding checking my room for spiders and I put hoodies under the door so spiders cant get in while I sleep, i also compulsively check my body for signs of illness (I still do both these things but its not as bad as before). So I finally went to the GP who put me on meds, I was on them for a week and they made it worse so I stopped and got put on the waiting list for a psychologist but I was told it would be 3 months before I got an appointment ( i have been told this will be even longer wait now), so a few weeks later i went back to the GP to get different meds because I couldn't cope. I found that they started working in about a week and a bit and Im only on 10mg (a low dose) and I have noticed that my general anxiety had almost gone away (i still have bad days & panic attacks) and that even when I did get anxious it was much easier to control ( I couldn't control the anxiety at all before) While I still cant deal with people being sick and I go a bit over the top with sanitising stuff and making people wear gloves etc. It's much better and I feel guilty about this, I somehow feel as if that i'm not anxious and that i'm over reacting or just made it up and that it's all just in my head, I feel guilty for taking the medication because I feel like i'm just being stupid and thats theres nothing wrong with me, even though I was so scared all the time, i couldn't control my anxiety and I was having panic attacks every night begging my mum to take me to the ER at 1 in the morning. I know its stupid to feel this but for some reason I do, i just feel like because the meds worked quick, were very effective and were low dose that i'm overreacting and that i'm not anxious to be on meds.
