Hey, i'm new on here and just need someone to talk to really. I have health and general anxiety and also have thyroid disease. Anyway this has affected my long term relationship and I feel like i'm about to lose him and feel like i cant survive alone. I have had no libido for a long time now, not sure if due to anxiety, thyroid or what. Anyway we dont sleep together and hes getting very fed up and im pretty sure he will leave me soon and im so scared. We havent spoken for 2 days now and ive tried to speak to him but today he just drove out somewhere without saying anything and now im just crazy anxious now just waiting for him to come back and no idea if he will come back even. We live together btw. I just feel helpless and cant calm down 
Anxiety affecting libido is quite common. It's probably worth talking to your doctor about. It's a shame your partner isn't more understanding and it's him that's in the wrong for making you feel bad for not sleeping with him, not you. Clearly this issue is making your anxiety worse, and I'd suggest sitting down with him and explaining when he's a bit more rational.

Supposed problems with Libido can be caused by Anxiety or certain medications you may be taking to control your Mental Health. Thyroid medications MAY cause problems so you nee to talk to your GP.
I would suggest you read the instruction sheet in with your medications that may explain any relevent side effects. You can also look in the NHS CHOICES webpages and check your medications there and any contraindications that may also effect you sexual appetites. Do Not Use The Site For any other queries you may have, you nee to talk to your Doctor for those.
However personally I would discuss all with your man and if need be see your Doctor together if you feel it is all to do with your relationship together

My girlfriend and I have been dating for four years in total, she has mood swings everyday & has a very low sex drive I'm cool with that I love her for her.
Dump your boyfriend if he is going to leave you because he can't get sex then he clearly isn't worth it afterall.
Speak to him about it be open tell him that it's not your fault you suffer from anxiety and it's not in your hands.
If he still gives you attitude regarding to your problem dump his ass.
