tips to put yourself in the mood?

I (21f) have been with my boyfriend (22m) for a year and a half, but we haven’t had sex in almost six months, despite living together. During this time, I have had serious struggles with my mental health and anxiety surrounding sex, which have destroyed my libido. We thought it was a side effect of the antidepressants and anxiety medication I was taking, but I have been working with a psychiatrist and therapist and taking several different pills and have not experienced a change. I would really appreciate some advice on how to put myself in the mood so that I can finally do this for him. Taking any and all suggestions 🙂 TIA
