LGBTQ couples face the very same struggles as heterosexual couples do. Being at a different stage of coming out though and stigma are factors that could act as additional stressors for LGBTQ partners.
At the individual level things might be a bit different. You might be feeling confused and anxious over your sexual orientation. You might be struggling with coming out and might feel lonely and isolated. You might be experiencing discrimination or you might be struggling with homophobia (external or internalized). You might be having dysphoria around your gender identity and you might be considering hormone replacement therapy or a sex change so you can look more like how you feel inside.
Finding a knowledgeable and informed therapist for LGBTQ Couples Counseling can provide you with support and facilitate your transition to a more authentic life.
