TTC struggles

Me and my husband have been trying for a baby for 4 years:( in September we are starting IVF and as anxious I am to start I'm also very scared. Lately  I am not dealing very good with not being able to get pregnant. Although my husband is very supportive I feel very lonely and feel like everything is getting on top of me. I just wondered if anyone else feels or felt like that or is it just me....
