Need to Improve my Communication Skills in Relationships and In general as this is causing frustration

Hello everyone its me Lost Angel this Post is a mix of venting and to give myself some reasurance and litterally just work out how to move forward with how to communicate more effectively with those around me,firstly I can become so scared of what someones reaction could be about something that I either hesitate or run or think too much about my actions without following through with my actions cause of fear that it may cause some kind of conflict either for both me and the person Im trying to talk to as well as just mainly being to worried about the other person may feel so I hesitate to take action sometimes even fail to take action that wouldnt be negative I can too easily turn a positive into a negative especially during lockdown and since boredom has set in but besides that I just need to take the leap inspite of fear and reachout anyway to the other person ,I feel like Im always inconsistent and lacking in starting conversations in particular with special someone its like I feel its better to give space even though I should be putting myself out there to make converstion and then I fall into a slump of waiting and waiting rather than doing the one thing or saying the one thing that I want to do or say then later I doubt myself again for not taking the right actions at the right time or what would have been the right time but I messed it up and failed to do so
