You improve them by stopping overthinking about every think . From what I've been reading you are not the anxious type , but extremely anxious . You for sure have a anxiety , and panic disorder and the stress one. For me , I got over the problem of having anxiety and panic disorder by saying in my head that is all gonna be fine . Just focusing on that thought . The fact that you said you were shaking typing these texts makes it clears that you have stress disorder and panic . Which I know is a bitch but it can be overcome .

The fact that you already think you have 70 percent chances of doing it wrong is already damaging and anxious thinking. Just let shit flow and maybe it will be better . Also tell your husband to chill out and stop groping you . He doesn't help at all . Do you take anxiety pills ? Meditations helps a lot in these cases .

Sitting in a quiet place and just thinking postive about what you want from life . Not " oh is gonna go wrong , if it happens what do I do ? What if I hurt their feelings ? " Working out helps a lot .And is refreshing from anxiety . Anxiety only lowers the libido .
