Hello Motoko353, along with RT can I welcome you to the forums.
Can I suggest you go back to your GP and have your medication reviewed because if it's affecting your sex drive then you won't be able to concentrate on the issues you need help with.
I had the same problem a long time ago so my doctor immediately stopped prescribing that particular medication and started me on a new one.
